The Apostle Paul wrote an amazing contrast in 2 Corinthians 4:16-18, which says:
“So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.”
On the one hand, there are things that are transient, described as: outer, wasting away, light, momentary, affliction, and seen.
On the other hand, what is eternal is: inner, being renewed, weighty, glorious, beyond all comparison, and unseen.
These things are part of each of us, but what is eternal matters infinitely more than the other. Don’t confuse the two, or you may lose heart because Paul earlier assured us in verse 14 that “he who raised the Lord Jesus will raise us also with Jesus and bring us with you into his presence.” At that time, only what is eternal will remain.
