For thy lovingkindness [is] before mine eyes
The special lovingkindness of God, shown in the choice of him in Christ, in the provision of a Saviour for him, and in the effectual calling of him; which lovingkindness is unmerited, free, and sovereign, is from everlasting and to everlasting; it is better than life, excellent beyond expression, and marvellous: and this may be said to be "before [his] eyes"; because it was now in sight; he had a comfortable view of interest in it, and was persuaded nothing should separate him from it; it was upon his heart, shed abroad in it, and he was affected with it; it was in his mind, and in his thoughts, and they were employed about it; he had it in remembrance, and was comfortably refreshed with it: and this he mentions as the reason of his laying his cause before the Lord, as the ground of his trust in him, and why he desired to be examined, proved, and tried by him;
and I have walked in thy truth;
by faith in Christ, who is the truth of all promises, prophecies, types, and figures; in the word of truth, by abiding by it, and walking according to it; and in the truth of worship, in all the commandments and ordinances of the Lord; and to walk herein he used himself to, and was constant in, as the word F19 signifies: and nothing more engages to walk on in Christ, as he has been received and to walk as becomes his Gospel, and in all holy conversation and godliness, than the love of God manifested to the soul; this being set continually before our eyes encourages faith and hope, and influences a holy life and cheerful obedience to the will of God.
