2 Corinthians 5:4
For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life. For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life.
Those who are in this earthly tabernacle, this earthly house, groan while burdened, earnestly desiring the heavenly house from God, and if the earthly house is dissolved they have a building of God eternal in the heavens. Not wanting to be unclothed or left naked means the hope is not bodiless existence without life, but to be clothed upon with the eternal heavenly house from heaven, which is immortal life. Mortality is swallowed up of life when the dead rise at the resurrection.
That swallowing up comes at the glorious resurrection, when the Life-giver breaks the tomb's hold and calls the dead to immortal life. Even though a believer may die, the life of Christ in him is eternal by feeding on Christ, and he will be raised up at the last day. The verse is a precious utterance and a large and full promise of eternal life in Christ that gives strong consolation and comfort without human help. It belongs to the daily banquet of God's Word to be fed upon every day for an experience of highest value, showing God's Word to be as wheat to chaff beside the word of man.
The verse's hope assures that a faithful wife will rise at the resurrection and be reunited with her companion. Until mortality is swallowed up of life, repentance remains a daily continuing exercise. As evidence of God's favor becomes clearer, the penitent sees more to regret in past sin, loathes and condemns himself for remaining in rebellion, and values Christ's righteousness above earthly wealth and ties.
