Clearly, grace is God Himself coming in the person of Christ. The fullness of Christ is dispensed to His believers in waves of grace. Grace is thus the continuous dispensing of God Himself in Christ. The Epistles make this very clear. Grace here is equated with Christ and is in fact personified.
Grace is personified as a trainer.
It is God in Christ as the Spirit, daily received and enjoyed, that trains us to live soberly in this age. In two more instances grace is synonymous with Christ. When we have Christ with our spirit, we have grace with our spirit, and when we are empowered in the Lord, we are empowered in grace. Paul's Epistles stress the believers' subjective and intimate experience of Christ. Whereas the Gospels and Acts mention grace six times and eleven times respectively, Paul's Epistles mention grace ninety-eight times.
