NOTES for Psa 17:5

David says that even upon the assurance of the correctness of the way, his steps are not too firm sometimes, - footsteps slip. Man is a complex being, and his firmness in one thing doesn’t abolish fear in another. Thus, the taken decision to serve the neighbor doesn’t abolish fear before pain. And in this prayer, David asks God to strengthen him particularly in what he cannot cope himself. It is very important that we realize our weakness, our inability to cope with life without God, and open them to God in prayer, - then the Lord can assert us, bestow us His power, because the power of God is fulfilled in our infirmities (see 2 Cor. 12:9).
