The confession of holy men is this:
By the grace of God I am what I am: and His grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me.
1 Corinthians 15:10
The grace of God is always without measure upon His own so that they might labour abundantly in that which pleases the Lord. There is no man truly knowing the grace of God who will not labour to some degree; and when he has laboured, he will ascribe the good only to the glory of the grace of his Maker. And the greater he labours by faith in what is hoped for, the more grace yet unseen he discovers; according to which grace he may continue proving by obedience what is the will of God, his sanctification.
Give unto the Lord the glory due unto His name; worship the Lord in the beauty of holiness.
