J. N. Darby

We have in the Lord here - wisdom, discernment, and knowledge (v. 19, 20). Then the young man (the son of wisdom) is to keep counsel, a new word (chap. 2:7), and prudence: the last we have had at the end of chapter 1:4. It shall be comeliness even in the eyes of others, as well as life inwardly, that is, the power and enjoyment of life in the soul. It shall make us walk safely and not stumble in the way; it is the daylight of which the Lord speaks, the path of God where God is (compare John 11:9-10; Phil. 4:8-9); and, when we lie down, it shall be in felt safety and peace. This leads to another point - the way in which, so walking, confidence in the Lord is maintained in the heart, "If our heart condemn us not, then have we confidence towards God." A stranger from God in this world, the power of evil is in the world; and fear accompanies, for the spirit of man, its unknown course, and the secret power that guides it. Walking in holy subjection before God, which is our wisdom, we can confide in Him, who is over all, without whom not a sparrow falls to the ground. It is not that we know what is coming, but that we know that the Lord is there, who rules and orders all. Nothing happens for us: God's hand is in everything; and we confide in Him. Indeed everything will work together for good. At any rate, we confide in Him.
