How does the enemy of God, unable to please God, unable to submit per Romans 8, and dead in their sins per Ephesians 2, do anything alive, nevermind produce faith?
Where does faith come from? "faith comes from hearing, and hearing through the word of Christ".
Faith comes first then the forgiveness of sins and the new life.
"And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him"
How was anyone born again prior to the glorification of our Lord Jesus Christ?
Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.’” Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified. (Joh 7:38-39)
This Jesus God raised up, and of that we all are witnesses. Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this that you yourselves are seeing and hearing. (Act 2:32-33)
And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. (Act 2:38)
Knowing the Spirit of the Lord had not been given yet to believers of God, then how did one before the advent of Christ please God being in an unregenerate state?
The biblical answer to pleasng God is "by faith".
