The Earnest Of The Spirit

2 Corinthians 5:

1 For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens.
2 For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven:
3 If so be that being clothed we shall not be found naked.
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.
5 Now he that hath wrought us for the selfsame thing is God, who also hath given unto us the earnest of the Spirit.

2 Cor.5:1-5
