2 Corinthians 5:5 Now he that hath wrought us for the selfsame thing is God, who also hath given unto us the earnest of the Spirit.

The greatest event that is coming is the rapture of the church. Christ will receive His church into glory. Most significantly, it will be the day of the redemption of the body.

The Apostle Paul tells us concerning eternal blessings in Christ in Ephesians 1:11-14 In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will: That we should be to the praise of his glory, who first trusted in Christ. In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.

The event of the rapture itself is well described by the Apostle Paul in 1 Thessalonians 4:13-18 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. Wherefore comfort one another with these words.
