Job 17:9: The righteous also shall hold on his way, and he that hath clean hands shall be stronger and stronger.
Thomas Watson
“Question: What is it, to walk with God? Answer: Walking with God imports five things: 1. Walking as under God's eye. Noah reverenced God. A godly man sets himself as in God's presence, knowing that his judge is looking on: "I have set the Lord always before me" (Psalm 16:8). David's eyes were here. 2. The familiarity and intimacy which the soul has with God. Friends walk together and console themselves with one another. The godly make known their requests to God and he makes known his love to them. There is a sweet fellowship between God and his people: "Our fellowship (koinonia) is with the Father, and with his Son Jesus Christ" (1 John 1:3). 3. Walking above the earth. A godly man is elevated above all sublunary objects. The person who walks with God must ascend very high. A dwarf cannot walk among the stars, nor can a dwarfish, earthly soul walk with God. 4. Visible piety. Walking is a visible posture. Grace must be conspicuous to the onlookers. He who reveals something of God in his behavior, walks with God. He shines forth in biblical conduct. 5. Continued progress in grace. It is not only a step but a walk. There is a going on towards maturity. A godly man does not sit down in the middle of the way but goes on until he comes to the "end of his faith" (1 Pet. 1:9). Though a good man may be out of the path, he is not out of the way. He may through infirmity step aside (as Peter did)—but he recovers by repentance and goes on in progressive holiness: "The righteous will hold to their ways, and those with clean hands will grow stronger" (Job 17:9).” ― Thomas Watson, The Essential Works Of Thomas Watson
