"And you were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience— among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved— and raised us up with him and seated us with him in the heavenly places in Christ Jesus, so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them."
It is a good thing to understand we have nothing to do with our salvation because we were incapable, considering we were DEAD. Totally, spiritually "DEAD"... as a doornail. Apart from God we cannot produce ANYTHING of eternal profit as stated by Noah Webster:
8. Unemployed; useless; unprofitable. A man's faculties may lie dead, or his goods remain dead o his hands. So dead capital or stock is that which produces no profit.
As I comprehend how dead I was, can I more fully appreciate what God has done in my life. He has raised me from the dead. He moved me. He opened my blind eyes which could not by their own power see His provision for me.
How can I describe it more... Glory to God alone.
