He will not let your foot slip. When you are in a time of prosperity, a time of confidence and self assurance, the thought of slipping seems far away and this truth only receives a fleeting glance. It is only when you feel the bite of life, the pain and exhaustion of struggles that the words of the writer are a comfort and consolation to the soul. I would not wish struggles and trials on anyone, but life has many of them. A man who has never had a trial has never lived or is completely deceived. We don’t revel in them, but like all things it is a matter of where we fix our eyes. In football you are told to keep you eye on the ball, in the Lord we are to fix our eyes on him. One of the purposes of trials is that we learn to fix our eyes on Him, the one whom the waves and the wind obeys. The trial purges us of earthly trust, of trust in the natural realm and the strength of man, so we can rely on the Lord, knowing that He will not let our foot slip, He will not cause us to stumble. Like Peter when he got out of the boat, he looked to Jesus. I find hope in this verse that it is His doing, it is Him, He is the one who will not let our foot slip. He is the one who watches over you, the one who does not slumber. He is my protector despite the trials of life. Not that he spares us from them, but that he sustains us in them so that we become more than conquerors.
