That is tough. Romans 8:20-21 For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope, [21] Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
Vanity and the bondage of corruption...delivered into the glorious liberty of the children of God. I’ll try not to ramble. He said to set our affection higher on the New Jerusalem, on the world to come and not this one. That we are just passing through. At the same time, the earth in the bondage of corruption is promised deliverance. Same as the body. You are pointing at delivernace from Spiritual death instead of physical because ‘immortality’ you caution at, yeah? But part of the corruption is linked to physical death and man’s quest to consume all he can before his time is up and someone else enjoys his hard earned labour. We watch wrinkles and decay and deterioration of our bodies and the earth also under the bondage of corruption. All are promised deliverance from death. There is the mention of where moth do not eat and destroy. But then I also pause at even calling decay bad since it can also be good. Only God knows. Bondage of corruption...without vanity, sin and death. Evil, death, and cursing swallowed up in victory by Life, good, and blessing. What is the vail covering eyes so they see not?
Do heed your warning though at “immortality”. Been thinking about all man does to obtain “immortality” of their god(s). In ancient times breaking the jaws of corpses and shoving things down their throats in belief of a safe passage into an afterlife and immortality. Thought a lot about it actually since you mentioned it as a possible fear of death...which in itself is vanity. 1 Timothy 1:17 Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen.
Can say I have wanted to be wise. Can say I have wanted to eternal and immortal. Can’t say I have ever wanted to be invisible. Kind of get, maybe, your hinting at man’s long time quest to be AS God...don’t know the answer to your intital question.
