Man without God's enabling power of grace, to control his flesh, is incapable of doing divine good.
Adam before the fall was capable of doing good.
God has sovereignly arranged for fallen men, when they are placed into God's saving grace.
Are made able to make a choice to believe in Jesus.
Not all believe.
For the grace of God that brings salvation has appeared to all men, teaching us that,
denying ungodliness and worldly lusts, we should live soberly, righteously, and godly
in the present age. Titus 2:11-12
What can I say?
That is what the Word of God says.
For the grace of God that brings salvation has appeared to all men.
Stick with the Word!
