Then please, differentiate the two.
Tribulation is a testing of the faith. A refining or the gold and silver of what God has produced in us through sanctification. Wrath is God’s judgement and punishment poured out on sinners.
Jesus promised believers tribulation in John 16:33 I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world.”
Revelation 7:14 I said to him, “Sir, you know.” And he said to me, “These are the ones coming out of the great tribulation. They have washed their robes and made them white in the blood of the Lamb.
Tribulation is promised to believers, believers go through the tribulation in Revelation.
