Psalms 93:18

8. So Peter also said, “Bid me come unto Thee on the water.” I who dare this am but a man, but it is no man whom I beseech. Let the God-man bid, that man may be able to do what man cannot do. “Come,” said He. And He went down, and began to walk on the water; and Peter was able, because the Rock had bidden him. Lo, what Peter was in the Lord; what was he in himself? “When he saw the wind boisterous, he was afraid; and beginning to sink, he cried out, Lord, I perish, save me.” When he looked for strength from the Lord, he had strength from the Lord; as a man he tottered, but he returned to the Lord. “If I said, my foot hath slipped” (they are the words of a Psalm, the notes of a holy song; and if we acknowledge them they are our words too; yea, if we will, they are ours also). “If I said my foot hath slipped.” How slipped, except because it was mine own. …

6. Therefore, to finish this discourse with that with which we began it, let us pray, and let us rely on God; let us live as He enjoineth; and when we totter in this life, let us call upon Him as the disciples called, saying, “Lord, increase our faith.” Peter both put his trust in Him, and tottered; but notwithstanding he was not disregarded and left to sink, but was lifted up and raised. For his trust whence was it? Not from anything of his own; but from what was the Lord’s. How? “Lord, if it be Thou, bid me come unto Thee on the water.” For on the water was the Lord walking. “If it be Thou, bid me come unto Thee on the water.” For I know that if it be Thou, Thou biddest, and it is done. “And He saith, Come.” He went down at His bidding, but in his own weakness he was afraid. …

17. “If I said, My foot hath slipt; Thy mercy, O Lord, held me up” ( ver. 18 ). See how God loveth confession. Thy foot hath slipt, and thou sayest not, my foot hath slipt; but thou sayest thou art firm, when thou art slipping. The moment thou beginnest to slip or waver, confess thou that slip, that thou mayest not bewail thy total fall; that He may help, so that thy soul be not in hell. God loveth confession, loveth humility. Thou hast slipped, as a man; God helpeth thee, nevertheless: yet say, “My foot hath slipt.” Why dost thou slip, and yet sayest, I am firm? “When I said, My foot hath slipt, Thy mercy, O Lord, hath held me up.” Just as Peter presumed, but not in strength of his own. The Lord was seen to walk upon the sea, trampling on the heads of all the proud in this life. In walking upon the foaming waves, He figured His own course when He trampleth on the heads of the proud. …

Lastly , the Author of our salvation teaches us what we ought not merely to think, but also to acknowledge in everything that we do. “I can,” He says, “of mine own self do nothing, but the Father which abideth in me, He doeth the works.” He says, speaking in the human nature which He had taken, that He could do nothing of Himself; and shall we, who are dust and ashes, think that we have no need of God’s help in what pertains to our salvation? And so let us learn in everything, as we feel our own weakness, and at the same time His help, to declare with the saints, “I was overturned that I might fall, but the Lord supported me. The Lord is my strength and my praise: and He is become my salvation.” And “Unless the Lord had helped me, my soul had almost dwelt in hell. If I said, My foot is moved: Thy mercy, O Lord, assisted me. …

Paphnutius : This would fairly influence us, if in every work and practice, the beginning and the end were everything, and there were no middle in between. And so as we know that God creates opportunities of salvation in various ways, it is in our power to make use of the opportunities granted to us by heaven more or less earnestly. For just as the offer came from God Who called him “get thee out of thy country,” so the obedience was on the part of Abraham who went forth; and as the fact that the saying “Come into the land” was carried into action, was the work of him who obeyed, so the addition of the words “which I will show thee” came from the grace of God Who commanded or promised it. …
