I have chosen the way of truth: thy judgments I have not forgotten.

“He who loves truth, and never utters a false word with his mouth, may say, "I have chosen the way of truth."  Moreover, he who always sets the judgments of God before his eyes, and remembers them in every action, will say, "Thy judgments have I not forgotten." And how is our heart enlarged by trials and afflictions! For these pluck out the thorns of anxious thoughts within us, and enlarge the heart for the reception of the divine laws. For, says he, "in affliction Thou hast enlarged me." Then do we walk in the way of God's commandments, well prepared for it by the endurance of trials.”

“But after he had said, "And pity me according to Thy law;" he mentioneth some of those blessings which he hath already obtained, that he may ask others that he hath not yet gained. For he saith, "I have chosen the way of truth: and Thy judgments I have not forgotten" (ver. 30). "I have stuck unto Thy testimonies: O Lord, confound me not" (ver. 31): may I persevere in striving toward the point whereunto I am running: may I arrive whither I am running! So then "it is not of him that willeth, nor of him that runneth, but of God that showeth mercy." He next saith, "I will run the way of Thy commandments, when Thou hast widened my heart" (ver. 32). I could not run hadst Thou not widened my heart. The sense of the words, "I have chosen the way of truth, and Thy judgments I have not forgotten: I have stuck unto Thy testimonies," is clearly explained in this verse. For this running is along the way of the commandments of God. And because he doth allege unto the Lord rather His blessings than his own deservings; as if it were said unto him, How hast thou run that way, by choosing, and by not forgetting the judgments of God, and by sticking to His testimonies? Couldest thou do these things by thyself? I could not, he replieth. It is not therefore through my own will, as though it needed no aid of Thine; but because "Thou has widened my heart." The widening of the heart is the delight we take in righteousness. This is the gift of God, the effect of which is, that we are not straitened in His commandments through the fear of punishment, but widened through love, and the delight we have in righteousness. ...”

“I will run the way of thy commandments,.... Not only walk but run in it; which is expressive of great affection to the commands of God, of great readiness and cheerfulness, of great haste and swiftness in the way of them, and of great delight and pleasure therein; when thou shall enlarge my heart; with the knowledge of God, his word, ways, worship, and ordinances; with his love more fully made known, and with an increase of love to him; with the fear of him, and a flow of spiritual joy and peace; and when delivered from straits and difficulties, from weights and pressures, and everything that may hinder walking or running; and being in circumstances which may lead and encourage to the one as to the other; see Kg1 4:29, Isa 60:5.”
