You did not choose God out of your own free will. God did not give you a new heart because you decided to have faith and repent of your sin. Your righteousness was given to you by Christ because you were chosen by God from eternityâ€”he is the only perfectly righteous personâ€”and not because you decided to invite Jesus into your heart.
Together with most of the other New Testament writers, Paul affirms that the last days were inaugurated in the first-century A.D. when Christ first came down from heaven. If this is true, then like the Thessalonians, we are to be equally steadfast and patient in our hope for Christâ€™s return.
Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord.
