Christians, does the Church replace Israel and is God done with them or are the just set aside for now?

No, because God has made an unconditional and eternal covenant with Israel. God’s unconditional promises are not invalidated by the unfaithfulness of some. Promises made to Israel are still going to be kept in the future. We can be sure that all God has said is true and will take place, because of His character and consistency. The Church does not replace Israel and should not expect a symbolic fulfillment of the promises of the Old Covenant As one reads Scripture, it is necessary to keep Israel and the Church separate.

I found an article (first link below) that discusses "replacement theology" in some detail. Jehovah's Witnesses, for example, claim Jehovah rejected Israel after Israel rejected Jesus and that a limited number of "anointed" Jehovah's Witnesses are "spiritual Israel" - they have replaced Israel. This is unbiblical.

Biblically speaking, the church is completely different and distinct from Israel, and the two are never to be confused or used interchangeably. We are taught from Scripture that the church is an entirely new creation that came into being on the day of Pentecost and will continue until it is taken to heaven at the rapture (Ephesians 1:9-11; 1 Thessalonians 4:13-17). The church has no relationship to the curses and blessings for Israel. The covenants, promises, and warnings are valid only for Israel. Israel has been temporarily set aside in God's program during these past 2000 years of dispersion.

After the rapture (1 Thessalonians 4:13-18), God will restore Israel as the primary focus of His plan. The first event at this time is the tribulation (Revelation chapters 6-19). The world will be judged for rejecting Christ, while Israel is prepared through the trials of the great tribulation for the second coming of the Messiah. Then, when Christ does return to the earth, at the end of the tribulation, Israel will be ready to receive Him. The remnant of Israel which survives the tribulation will be saved, and the Lord will establish His kingdom on this earth with Jerusalem as its capital. With Christ reigning as King, Israel will be the leading nation, and representatives from all nations will come to Jerusalem to honor and worship the King—Jesus Christ. The church will return with Christ and will reign with Him for a literal thousand years (Revelation 20:1-5).

In Revelation 20:1-7 it says six times that Christ's kingdom will last 1000 years. After the tribulation the Lord will return and establish His kingdom with the nation of Israel, Christ will reign over the whole earth, and Israel will be the leader of the nations. The church will reign with Him for a literal thousand years. The church has not replaced Israel in God's plan. While God may be focusing His attention primarily on the church in this dispensation of grace, God has not forgotten Israel and will one day restore Israel to His intended role as the nation He has chosen (Romans 11).

Read Romans 11 KJV which explains about the tribes of Israel, also known as the 12 sons of the man whose name was changed from Jacob to Israel.

The Gospel of Matthew answers much, and it's clear that Israel still has a special situation in how Christ spoke of it, and further details are best gained by reading through this gospel. You should really read, taking your time, from the start, so that when you arrive at any one part, you have the ongoing context to help convey it's real meaning.

No.

Romans 11:25-28

25 For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that blindness in part has happened to Israel until the fullness of the Gentiles has come in. 26 And so all Israel will be saved, as it is written:

“The Deliverer will come out of Zion,

And He will turn away ungodliness from Jacob;

27

For this is My covenant with them,

When I take away their sins.”

28 Concerning the gospel they are enemies for your sake, but concerning the election they are beloved for the sake of the fathers.

As a special nation, the nation of Israel was rejected by God because they rejected his son, Jesus.

Matthew 21:43

This is why I say to you, the Kingdom of God will be taken from you and be given to a nation producing its fruits.

Matthew 23:37, 38

“Jerusalem, Jerusalem, the killer of the prophets and stoner of those sent to her—how often I wanted to gather your children together the way a hen gathers her chicks under her wings! But you did not want it. Look! Your house is abandoned to you.

But faithful Israelites of old will be resurrected. (Acts 24:15)

In the first century many Jews accepted Jesus as the messiah. Today, many Israelites are accepting what the Bible really teaches about Jesus, and they are dedicating their lives to serve Jehovah, the father of Jesus.

Just as the Israelites of old were people for God's name, so there are people for Jehovah's name today.

Acts 15:14

Symʹe·on has related thoroughly how God for the first time turned his attention to the nations to take out of them a people for his name.

Acts 15:17

so that the men who remain may earnestly seek Jehovah, together with people of all the nations, people who are called by my name, says Jehovah, who is doing these things,

No replace, different roles/missions.
