All one has to do is look at ISIS and the persecution of Christians to know that tribulation and God's wrath are not the same..
Isa 13:10 The stars of heaven and their constellations will not show their light. The rising sun will be darkened and the moon will not give its light.
Matt 24:29-31 "Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken. 30 Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. 31 And he will send out his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of heaven to the other.
Mark 13:14-27 "But when you see the abomination of desolation standing where he ought not to be (let the reader understand), then let those who are in Judea flee to the mountains. 15 Let the one who is on the housetop not go down, nor enter his house, to take anything out, 16 and let the one who is in the field not turn back to take his cloak. 17 And alas for women who are pregnant and for those who are nursing infants in those days! 18 Pray that it may not happen in winter. 19 For in those days there will be such tribulation as has not been from the beginning of the creation that God created until now, and never will be. 20 And if the Lord had not cut short the days, no human being would be saved. But for the sake of the elect, whom he chose, he shortened the days. 21 And then if anyone says to you, 'Look, here is the Christ!' or 'Look, there he is!' do not believe it. 22 For false christs and false prophets will arise and perform signs and wonders, to lead astray, if possible, the elect. 23 But be on guard; I have told you all things beforehand.
24 "But in those days, after that tribulation, the sun will be darkened, and the moon will not give its light, 25 and the stars will be falling from heaven, and the powers in the heavens will be shaken. 26 And then they will see the Son of Man coming in clouds with great power and glory. 27 And then he will send out the angels and gather his elect from the four winds, from the ends of the earth to the ends of heaven.
Luke 21:25-28 “There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea. 26People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. 27At that time they will see the Son of Man coming in a cloud with power and great glory. 28When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near.”
Rev 6:12-14 I watched as he opened the sixth seal. There was a great earthquake. The sun turned black like sackcloth made of goat hair, the whole moon turned blood red, 13and the stars in the sky fell to earth, as figs drop from a fig tree when shaken by a strong wind. 14The heavens receded like a scroll being rolled up, and every mountain and island was removed from its place
