Explain....
I think most Christians understand what you're saying...
1Co 15:30 Why are we in danger every hour?
1Co 15:31 I protest, brothers, by my pride in you, which I have in Christ Jesus our Lord, I die every day!
1Co 15:32 What do I gain if, humanly speaking, I fought with beasts at Ephesus? If the dead are not raised, “Let us eat and drink, for tomorrow we die.”
These verses have been debated for as long as they've been published to others. Paul's doctrine was well know to those at Corinth. His letters to Corinth are often misunderstood because Paul had a history with the people to which he was writing.
Paul wasn't writing to people that he didn't know him in similarity to the situation when he wrote the book/letter of Romans. As such, there is a "broken/skipping" nature to what Paul wrote here in what we consider 1 Cor 15. They knew him well enough to clearly understand his writings. We are outsiders "looking in" to this conversation.
Discussing his letter to Corinth is like overhearing a conversation between friends or peers.....
In verse 31 (as we distinguish it) Paul is appealing not to the immediate context of the words written shortly before this. He was appealing to
1Co 15:21 For as by a man came death, by a man has come also the resurrection of the dead.
1Co 15:22 For as in Adam all die, so also in Christ shall all be made alive.
He is appealing to this "death" wrought in humanity through Adam. A unknown and unexpected finality brought to humanity through the faithlessness of Adam to trust/believe God. The finality of the struggle to bring about within humanity the willingness of mind to just trust God.
We have an enemy before us. An enemy that is unknown to us. The last enemy to our perfection is precluded by our death.
1Co 15:26 The last enemy to be destroyed is death.
The phrase "I die daily" is an appeal to the unknown nature of our end. Many many people are taken from this life because of the sins of others. Which is why I personally try to ask God to protect my own every day of my life.
The results of sin is not just a faithlessness from long ago in Adam. It is the present sin of others and our own sin. It is an inevitable uncertainty that requires our preparedness for death every moment of our lives.
Thusly..... "I die daily". Whether our own sin or the sins of others within our immediate lives, there is nothing more inevitable than the realty of our flesh ruling our members. Saved or not. Redeemed or not. Born from above or not.
Such is NOT perfection. It was never designed to be perfection. It is not the absence of sin whether personal sin or not. It is the circumstances of death all around us.
