"As a man does not make himself spiritually alive, so neither can he keep himself so. He can feed on spiritual food, and so preserve his spiritual strength; he can walk in the commandments of the Lord, and so enjoy rest and peace, but still the inner life is dependent upon the Spirit as much for its after existence as for its first begetting. I do verily believe that if it should ever be my lot to put my foot upon the golden threshold of Paradise, and put this thumb upon the pearly latch, I should never cross the threshold unless I had grace given me to take that last step whereby I might enter heaven. No man of himself, even when converted, hath any power, except as that power is daily, constantly, and perpetually infused into him by the Spirit. But Christians often set up for independent gentlemen; they get a little stock of grace in hand, and they say, "My mountain standeth firm, I shall never be moved." But ah! it is not long before the manna begins to be putrid. It was only meant to be the manna for the day, and we have kept it for the morrow, and therefore it fails us. We must have fresh grace." —C. H. Spurgeon (1834-1892)
