Peter was an expert in such matters, for he had had a bitter experience to teach him how soon and surely self-confidence became self-despair. Though all should forsake Thee, yet will not I,' was said but a few hours before he denied Jesus. His faith failed, and then the divine guard that was keeping his soul passed thence, and, left alone, he fell.
That divine Power is exerted for our keeping on condition of our trusting ourselves to Him and trusting Him for ourselves. And that condition is no arbitrary one, but is prescribed by the very nature of divine help and of human faith. If God could keep our souls without our trust in Him He would. He does so keep them as far as is possible, but for all the choicer blessings of His giving, and especially for that of keeping us free from the domination of our lower selves, there must be in us faith if there is to be in God help. The hand that lays hold on God in Christ must be stretched out and must grasp His warm, gentle, and strong hand, if the tingling touch of it is to infuse strength. If the relieving force is victoriously to enter our hearts, we must throw open the gates and welcome it. Faith is but the open door for God's entrance. It has no efficacy in itself any more than a door has, but all its blessedness depends on what it admits into the hidden chambers of the heart.
I reiterate what I have tried to show in these poor words. There is no noble life without our guarding our hearts; there is no effectual guarding unless God guards; there is no divine guarding unless through our faith. It is vain to preach self-governing and self-keeping. Unless we can tell the beleaguered heart, The Lord is thy Keeper; He will keep thee from all evil; He will keep thy soul,' we only add one more impossible command to a man's burden. And we do not apprehend nor experience the divine keeping in its most blessed and fullest reality, unless we find it in Jesus, who is able to keep us from falling, and to present us faultless before the presence of His glory with exceeding joy,'
