(5) Lead me in thy truth.--Better, make me walk in--i.e., make me to have an actual experience of the Divine faithfulness in my passage through life.

Verse 5. - Lead me in thy truth, and teach me. "Thy truth" would seem to mean here "the true, right path" - the "way of godliness." The prayer is that God will both teach this to the psalmist and "lead him in it" - cause him, i.e., to walk in it, and never stray from it, so long as he lives. For thou art the God of my salvation. Thou art the God from whom alone I obtain salvation, and to whom alone, therefore, I am bound to pray for everything on which salvation depends - as, for instance, light and guidance. On thee do I wait all the day. In prayer for these blessings, I wait on thee all the day long.

25:1-7 In worshipping God, we must lift up our souls to him. It is certain that none who, by a believing attendance, wait on God, and, by a believing hope, wait for him, shall be ashamed of it. The most advanced believer both needs and desires to be taught of God. If we sincerely desire to know our duty, with resolution to do it, we may be sure that God will direct us in it. The psalmist is earnest for the pardon of his sins. When God pardons sin, he is said to remember it no more, which denotes full remission. It is God's goodness, and not ours, his mercy, and not our merit, that must be our plea for the pardon of sin, and all the good we need. This plea we must rely upon, feeling our own unworthiness, and satisfied of the riches of God's mercy and grace. How boundless is that mercy which covers for ever the sins and follies of a youth spent without God and without hope! Blessed be the Lord, the blood of the great Sacrifice can wash away every stain.Lead me in thy truth, and teach me,.... Meaning the word of God, the Scriptures of truth; and the Gospel, which is the word of truth, and truth itself, John 17:17; and the sense is, either that God would lead him by his Spirit more and more into all truth, as contained in his word; or that he would lead him by it and according to it, that he might form his principles and his conduct more agreeably to it, which is the standard and rule of faith and practice: which leading is by teaching; and reasons urged for granting all the above petitions follow,

for thou art the God of my salvation; who, in infinite wisdom, contrived scheme and method of it in his Son, and by him effected it, and by his Spirit had made application of it to him: and since the Lord had done such great things for him, he hoped the requests he had made would be granted: he adds,

on thee do I wait all the day; or continually, in public and in private, attending to all the duties of religion, yet not trusting in them, but in the Lord; and therefore he entreated he might not be ashamed of his hope and expectation for deliverance and salvation.
