God gives grace from start to finish in a person's relationship with Him. It cannot be limited merely to justification and His forgiveness of our sins.
Grace implies empowerment for growth. It is the single most important aspect of our salvation, and His giving of it is completely unmerited on our part.
Forgiveness is only the beginning of the grace process, enabling us to grow to the stature of Christ. Paradoxically, grace puts us under obligation to obey.
The entire life of Christ was a manifestation of God's grace, revealing the nature of God by means of a life lived to give us an example to follow.
