We can know Christ will claim us as His for all time. "For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trumpet 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" (1 Thessalonians 4: 16-17).
