That is not answer that explains what the grace does. Its only waxing poetic.
The question: What does grace do? What is its power to do for man?
Grace in the Bible has various applications.
One is in bringing us to salvation....
Then after salvation to continue working in our lives to bring us to maturity in Christ.
And be growing in the grace and knowledge of our Lord and Savior Jesus Christ.
To Him be the glory both now, and to the day of eternity. Amen." 2 Peter 3:18
There is one truth about God's grace that applies in all phases of God's use.
Its "enabling power" for the powerless.
But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.”
Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me."
2 Cor 12:9
Grace is real power that God administers to those whom He chooses for the purpose of His plan.
Before regeneration..
Our natural fallen state was powerless to overcome the tyrannical dominance of our flesh over our soul.
Without God's grace? No one could be free to believe.
For the flesh craves what is contrary to the Spirit, and the Spirit what is contrary to the flesh.
They are opposed to each other, so that you do not do what you want." Galatians 5:17
While drawing us God's grace will push down our flesh's power that would otherwise dominate over our soul.
In doing that? Our soul is made to be free (by grace) to finally be able to choose what we want to believe.
And, if we found ourselves wanting to?
Grace also makes a soul equally free to reject God.
But this time, rejection comes freely from the soul without the flesh dictating the decision against God.
That soul, like Satan did, ends up making that evil choice freely. That is why God will punish as He will.
Those whom the Father is able to draw to a predetermined level which He sees as the point of completion?
That one will be ready. God will know that they will want to believe in Jesus. That is when the Father hands that soul over to the Son.
God created man in His image. (Gen 1:26-27)
To be in God's image means man is to reflect the nature of God.
To be a true reflection? God granted man his own area of sovereignty to be within a domain specified by God.
That sovereignty of man resides in his volition within a realm God designated for man to choose from.
Man's sovereignty is so absolute in how God created man in His image?
That God Himself can not change our mind if we should end up resenting Him and wanting no part of Him...
In that manner God has truly created man in His image. Having sovereignty within a realm of choosing determined by God.
For now.....
grace and peace!
