Notice, it is the free gift of God. "Grace be unto you, and peace, from God our Father, and from the Lord Jesus Christ. I thank my God always on your behalf, for the grace of God which is given you by Jesus Christ." Paul wrote fourteen Epistles; and every one of them is closed with a prayer for grace. Paul calls it "The free gift of God." Thousands have been kept out of the kingdom of God because they do not realize what this free gift is. They think they must do something to merit salvation.
The first promise given to fallen man was a promise of grace. God never promised Adam anything when He put him in Eden. God never entered into a covenant with him as He did with Abraham. God told him "of the tree of the knowledge of good and evil thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die;" but when this came to pass then God came and gave him a gracious promise. He dealt in grace with him. As he left the Garden of Eden he could say to Eve, "Well, God does love us, though He has driven us out." There was no sign that Adam recognized his lost condition. As far as we know there was no cry for mercy or pardon, no confession of sin. Yet we find that God dealt in grace with him. God sought Adam out that he might bestow His grace upon him. He met Adam in his lost and ruined condition, and the first thing He did was to proclaim the promise of a coming Saviour.
For six thousand years, God has been trying to teach the world this great and glorious truth--that He wants to deal with man in love and in grace. It runs right through the Bible; all along you find this stream of grace flowing. The very last promise in the closing chapter of Revelation, like the first promise in Eden, is a promise of grace: "Whosoever will, let him take the water of life freely." So the whole revelation, and the whole history of man is encircled with grace, the free favor of God.
Some years ago when I was speaking on this subject, a friend sent me the following: "By the grace of God I am what I am!" This is the believer's eternal confession. Grace found him a rebel--it leaves him a son. Grace found him wandering at the gates of hell--it leads him through the gates of heaven. Grace devised the scheme of Redemption: Justice never would; Reason never could. And it is grace which carries out that scheme. No sinner would ever have sought his God but 'by grace.' The thickets of Eden would have proved Adam's grave, had not grace called him out. Saul would have lived and died the haughty self-righteous persecutor had not grace laid him low. The thief would have continued breathing out his blasphemies, had not grace arrested his tongue and tuned it for glory.
"'Out of the knottiest timber,' says Rutherford, 'He can make vessels of mercy for service in the high palace of glory.'"
"'I came, I saw, I conquered,' says Toplady, 'may be inscribed by the Saviour on every monument of grace.' 'I came to the sinner; I looked upon him; and with a look of omnipotent love, I conquered.'"
My friend, we would have been this day wandering stars, to whom is reserved the blackness of darkness--Christless--hopeless --portionless--had not grace invited us, and grace constrained us.
