You and others confuse the Rapture with the Second Coming. Two different events. Just as you confuse the Church with Israel.
Why would the Church go through the Tribulation period? It is for Israel, not the Church. It is the time of Jacobs trouble. (Jer. 30:7) Not the time of the Churches trouble.

Times of Jacob's Trouble
Jeremiah 30 vs. 1, 2 starts out with the Lord speaking to Jeremiah about Judah an Israel. Vs 3 the Lord promises that one day in the future as the day will come that He will bring Judah and Israel back to the land He had promised to their forefathers. Vs. 5 describes a time of great fear and trembling. Vs. 6 describes this time in a way that pictures men going through the pains of childbirth, meaning great agony. Vs. 7 For that day is great so that no other day will ever be like it. This is a reference to Matthew 24:21; Rev 7:1-8. But, there is hope for Judah and Israel for though this is called the time of Jacob's trouble the Lord promises He will save Jacob (referring to Judah and Israel, not literally Jacob) out of this time of great trouble, Rev 19:11-21. Vs. 8 It shall come to pass in that day (in that day means a future day) says the Lord that He will break his yoke from off their necks and will burst thy bonds and strangers shall no more serve themselves of him. His yoke is that of Satan who for now controls the evil principalities of this world that even today until Christ returns persecutes God's people. Vs. 9 But they shall serve the Lord their God and David their King, meaning Jesus whom God will raise up (resurrection) unto them. Vs 10, 11 the Lord says, I will surely save you out of a distant place, your descendants from the land of their exile. Jacob will again have peace and security and no one will make him afraid. I am with you and will save you declares the Lord.
Rapture/Catching up of the Saints
The catching up of the saints, meaning those alive at His coming and those who are in their graves will be changed and raised up together to meet Jesus in the air as this happens at the second coming of Christ on the last day when Christ returns and makes an end to all abominations here on earth, Matthew 24:29-31; John 5:28, 29; 6:40; 1 Corinthians 15:50-58; 1 Thessalonians 4:13- 18; Rev 19:11-21
