How Can I Start a Spiritual Conversation with a Jewish Friend?

Romans 11:11 says that salvation has come to the Gentiles to make Jewish people jealous. The most important thing we can do is to provoke jealousy. Jewish people are not sitting around saying, “I wonder if Jesus really is the Messiah.” They are thinking about the things that people would be concerned about, like kids or their grandkids. They’re hoping that they get into a good school or get a good job. They are concerned about issues other than whether or not Jesus is the Messiah. What we are called to do is to provoke them to want to be interested in Jesus, to provoke them to jealousy, not to provoke them to anger. I think the best way to do that is by being a good and loving friend.

And what do we do with friends? We talk about things that are near and dear to our hearts. Once you’ve established a good friendship with someone, one of the things that you can do is share what God is doing in your life. Love your friends and be concerned about them. If they don't ever express interest, you say, “I’ve been talking with you about all that God is doing in my life. Have you ever wondered about that?” And maybe they would be interested in your life as well.

Romans 11:11

¹¹ I ask, then, have they stumbled in order to fall? Absolutely not! On the contrary, by their stumbling, salvation has come to the Gentiles to make Israel jealous. (HCSB)

From the Moody Bible Commentary:

Stumble (v. 11) refers to Israel’s temporary spiritual setback, but her condition was not a permanent fall. God’s hardening of Israel, and Israel’s refusal to believe in Jesus as their Messiah, was ordained by God to provide time for the spread of the gospel to the Gentiles (vv. 11, 12, 15). Just as God’s fame spread as a result of Pharaoh’s hardening (cf. the note on 9:17-18), so also His fame was spreading to the Gentiles in Paul’s day because of Israel’s rejection of the gospel. As Gentiles embrace the Jewish Messiah and receive the accompanying blessings, God’s and Paul’s aim thereby was to make them [the Jewish people] jealous (lit., “to provoke them to be envious” so that they will imitate the Gentiles). Paul was intensely burdened that the Jewish people come to Christ, for when they do, the world will erupt in spiritual vitality and life (vv. 12, 15; cf. Is 27:6).

Is Climate Change Connected to Luke 21 and End Times Prophecy?

What Luke 21:25–36 is talking about is actually an allusion back to Joel 2:28–32, where it says there will be celestial signs during the Day of the Lord, which will culminate with the return of the Lord Jesus. Read the Book of Revelation, and it describes this as well.

This isn’t about climate change. I think that there really is climate change happening. But I also think that the climate changes all the time. There was a mini ice age in the Middle Ages. I’m not trying to minimize it. I don’t know how much human beings cause it, but we may very well be causing some of it. Nevertheless, I don’t think we can stop it, though people say that we should. When we’re looking at Luke 21, it’s not talking about climate change; it’s talking about God’s actions in the heavens.

Joel 2:28–32

²⁸ After this
I will pour out My Spirit on all humanity;
then your sons and your daughters will prophesy,
your old men will have dreams,
and your young men will see visions.
²⁹I will even pour out My Spirit
on the male and female slaves in those days.
³⁰I will display wonders
in the heavens and on the earth:
blood, fire, and columns of smoke.
³¹The sun will be turned to darkness
and the moon to blood
before the great and awe-inspiring Day of the Lord comes.
³²Then everyone who calls
on the name of Yahweh will be saved,
for there will be an escape
for those on Mount Zion and in Jerusalem,
as the Lord promised,
among the survivors the Lord calls. (HCSB)

Luke 21:25–26

²⁵ “Then there will be signs in the sun, moon, and stars; and there will be anguish on the earth among nations bewildered by the roaring sea and waves. ²⁶ People will faint from fear and expectation of the things that are coming on the world, because the celestial powers will be shaken. (HCSB)

From the Moody Bible Commentary:

Joel 2:28–32. After this indicates events in the distant future. This prophecy relates not to the return from the Babylonian captivity but to the eschatological day of the Lord (Acts 2:17 renders it “and it shall be in the last days . . .”). There are three characteristics of the eschatological renewal promised here. First, there will be an outpouring of God’s Spirit on Israel (vv. 28–29). This will come upon their sons, daughters, old and young men, and male and femaleservants so that they all will prophecy and have prophetic dreams . This will be a change from a limited office of prophet to a wide range of people who will have the Spirit of the Lord and will fulfill Moses’ hope for Israel (cf. Nm 11:29).

Second, there will be supernatural phenomena in the skies: These cosmic wonders will include wonders in the sky and on the earth, blood, fire, and smoke, the sun and the moon darkened at the time of the great and awesome day of the Lord (vv. 30-31). Such events are often associated with the future tribulation (cf. Is 13:9-10; 34:4; Mt 24:29; Rv 6:12; 8:8-9; 9:1-19; 4:14-20; 16:4, 8-9).

Third, there will be great deliverance at that time for whoever calls on the name of the LORD. This seems to be an invitation to escape the wrath of God spoken of at the start of the chapter (cf. Jl 2:1–11). The prophet promises escape for those on Mount Zion and in Jerusalem (cf. Rv 14:1–5) and seems to refer to the eschatological deliverance, both physical and spiritual, of Israel at the return of Christ (Zch 12:10; 14:3-5; Rm 11:26-27).

Luke 21:25–26. Jesus described the days prior to the second coming itself as days of upheaval—cosmic, 21:25a, 26b (cf. Jl 2:30-31; Ac 2:19-20a); international, Lk 21:25b; terrestrial, 21:25c; and social, 21:26a (cf. Rv 15-19). “Humans will be overcome by fear” (Bock, Luke, 1683).

Why Is David Called “The Man After God’s Own Heart” Despite All His Failures?

We know why David is called a man after God’s own heart. He cared about God tremendously. You see it in 1 Samuel 15, where Saul loses the kingdom because he won’t do his duty regarding Agag, the king of Amalek. Because Saul lost the kingdom, God sends Samuel to anoint David. Remember that Samuel is eager to anoint each of the brothers. That is where we learn that man looks at the outward appearance, but God looks at the heart. God saw something in David’s heart. And that’s why, right there, sort of out of chronological order, you get 1 Samuel 17, which explains what was in David’s heart when Goliath was taunting Israel and taunting the God of Israel. David hears with understanding what Goliath is saying and was concerned for God’s reputation. That is what God saw in David’s heart. Not only was he a man who had a heart for God, but God chose him. It’s election by grace. Though he had flaws, he became the ideal king. David was a great administrator, a gifted leader, and he had concern for everyone. Every king is measured against him.

1 Samuel 15:1–7

¹ Samuel told Saul, “The Lord sent me to anoint you as king over His people Israel. Now, listen to the words of the Lord. ²This is what the Lord of Hosts says: ‘I witnessed what the Amalekites did to the Israelites when they opposed them along the way as they were coming out of Egypt. ³ Now go and attack the Amalekites and completely destroy everything they have. Do not spare them. Kill men and women, children and infants, oxen and sheep, camels and donkeys.’”

⁴ Then Saul summoned the troops and counted them at Telaim: 200,000 foot soldiers and 10,000 men from Judah. ⁵Saul came to the city of Amalek and set up an ambush in the wadi. ⁶ He warned the Kenites, “Since you showed kindness to all the Israelites when they came out of Egypt, go on and leave! Get away from the Amalekites, or I’ll sweep you away with them.” So the Kenites withdrew from the Amalekites.

⁷ Then Saul struck down the Amalekites from Havilah all the way to Shur, which is next to Egypt. (HCSB)

From the Moody Bible Commentary:

Although Samuel continued to grieve over Saul’s disobedience, God was ready to do something new. This is a momentous point in the narrative, bringing onto the scene the central character of the rest of 1 Samuel and all of 2 Samuel. Saul did not have God’s will, interests, and glory at heart, so God selected a person who did—a shepherd boy who became the shepherd of all of Israel (cf. 2Sm 5:2, Brueggemann, First and Second Samuel, 119).

16:6-7. Observing Eliab, Jesse’s eldest son (cf. 1Ch 2:13), Samuel concluded, Surely the Lord’s anointed is before Him. Samuel may have thought of Saul’s impressive physical appearance, but that is not what the Lord was seeing. He was looking at the heart. He chooses His servants based on their inner lives, not on how they look.

Why Did David and Bathsheba Name Their Son Solomon When God Told Nathan to Name Him Jedidiah?

One of the things that you see about kings is they often have more than one title to reflect their nature. Consider the birth of Jesus, the Messiah. He is the Son of David and the King of Israel. He’s called Mighty God. He’s called Prince of Peace, Father of Eternity, and Wonderful Counselor. He’s also called Emmanuel. Those are throne titles. One of Solomon’s throne titles is Jedidiah, which means beloved of God and beloved of the Lord. That throne title reflects that God loved him in a very special way.

2 Samuel 12:24–25

²⁴ Then David comforted his wife Bathsheba; he went and slept with her. She gave birth to a son and named him Solomon. The Lord loved him, ²⁵ and He sent a message through Nathan the prophet, who named him Jedidiah, because of the Lord. (HCSB)

From the Moody Bible Commentary:

The birth of this child is part of the narrative strategy to trace the “Seed” of David. In fact, Solomon became David’s successor and heir to David’s throne. After learning about the special implications of God’s love for Solomon, David (or perhaps the prophet Nathan) gave Solomon an additional name, Jedidiah (“beloved of the Lord”).

What Does Romans 8:3 Mean When It Says God Condemned Sin In the Flesh?

Romans 8:3 says God condemns “sin in the flesh by sending His own Son in flesh like ours under sin’s domain, and as a sin offering.” The sin in the flesh requires condemnation, and it also requires payment in the flesh. The sins that we commit in the flesh deserve to be condemned. In order to be forgiven, our sins require payment in the flesh of a blood sacrifice. The law couldn’t provide that because the blood of bulls and goats don’t take away the condemnation of sin.

What about the physical sacrifice of the Messiah? He took the punishment that we deserved. Scripture says He became a sin offering. In 2 Corinthians 5:21 it says, “God made Him who knew no sin to be sin.” Jesus didn’t become sinful, but it means He became a sin offering. “He made Him who knew no sin to be sin [or to become a sin offering] for us, that we might become the righteousness of God in Him.” So our flesh deserves condemnation because of the sins we commit in it. God sent the Messiah in the flesh to take in His flesh the punishment that we deserve. He didn’t fulfill the Law by being sinless—He did so by the crucifixion.

Romans 8:3

³ What the law could not do since it was limited by the flesh, God did. He condemned sin in the flesh by sending His own Son in flesh like ours under sin’s domain, and as a sin offering, (HCSB)

From the Moody Bible Commentary:

Verse 3 provides a succinct summary of Rm 7 in which the main theme was the weakness of the law to help an unbeliever defeat sin’s power. For the meaning of flesh here and in 8:4, 5 (twice), 6, 7, 8, 9, 12, 13, cf. the comments on 7:5. Likeness of sinful flesh masterfully links Jesus closely with humanity because of His incarnation but maintains a distinction between His body and that of everyone else. He had real flesh, but it was not sinful flesh. Condemned sin in the flesh means that Jesus, through the medium of His sacrificed body, pronounced judgment on sin and broke its power. The law could only pronounce judgment but could not “execute” sin.
