In that day you will ask nothing of me. Truly, truly, I say to you, whatever you ask of the Father in my name, he will give it to you. John 16:23, ESV
Saving faith, the product of God’s grace (Romans 4:16; Ephesians 2:8–9) is possessed only by the regenerate. This faith is alive whereas before God’s grace quickened it, it was completely incapable and unwilling to believe in Christ as Lord and Saviour. This dead faith is inherited from Adam and the product of the fall (Genesis 3). Without God’s grace according with man’s faith, there is no possibility of belief and, therefore, no possibility of salvation. However, when God quickens a sinner (we are all sinners) his or her faith comes alive. The spiritual blindness that marked them before regeneration is washed away.
