“For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ, who died for us, that whether we wake or sleep,
we should live together with him.”
1 Thessalonians 5:9-10 

The rapture can happen at any time. It could happen today, tomorrow, or a hundred tears from now. There are many discussions as to the timing of the rapture in terms of last days’ events. Some believe that the rapture won’t happen until after the tribulation period (post tribulationists) and many believe that the rapture will happen before the tribulation period (pre-tribulationists).

When Paul uses the word “wrath” in the above text, he is referring to the Great Tribulation period. God has not appointed believers to experience His wrath upon the world which is what the Great Tribulation is, God’s wrath and fury poured out on an unbelieving and wicked world. Through the blood of Christ, we are given the spirit of mercy and grace. We are not in the same category with unbelievers, instead, we are set apart as God’s children with special privileges and protection!
