Taking Scripture out of context is how false teachings are promoted.
2 nd Corinthians 5:1-10
5:1 For we know that if the earthly tent which is our house is torn down, we have a building from God, a house not made with hands, eternal in the heavens. 2 For indeed in this house we groan, longing to be clothed with our dwelling from heaven; 3 inasmuch as we, having put it on, shall not be found naked. 4 For indeed while we are in this tent, we groan, being burdened, because we do not want to be unclothed, but to be clothed, in order that what is mortal may be swallowed up by life. 5 Now He who prepared us for this very purpose is God, who gave to us the Spirit as a pledge. 6 Therefore, being always of good courage, and knowing that while we are at home in the body we are absent from the Lord-- 7 for we walk by faith, not by sight-- 8 we are of good courage, I say, and prefer rather to be absent from the body and to be at home with the Lord. 9 Therefore also we have as our ambition, whether at home or absent, to be pleasing to Him. 10 For we must all appear before the judgment seat of Christ, that each one may be recompensed for his deeds in the body, according to what he has done, whether good or bad.
NAS
Taken in context vs. 8 is only part of Paul's teaching concerning the resurrection of the righteous dead to life immortal, not a teaching concerning a spiritual life in heaven. Therefore, instead of listening to false teaching that tickle your ears it is better to study God's truth in context. The Bible is clear that the Kingdom of God is an earthly Kingdom, not a kingdom in heaven.
