119:121-128 Happy is the man, who, acting upon gospel principles, does justice to all around. Christ our Surety, having paid our debt and ransom, secures all the blessings of salvation to every true believer. The psalmist expects the word of God's righteousness, and no other salvation than what is secured by that word, which cannot fall to the ground. We deserve no favour form God; we are most easy when we cast ourselves upon God's mercy, and refer ourselves to it. If any man resolve to do God's will as his servant, he shall be made to know his testimonies. We must do what we can for the support of religion, and, after all, must beg of God to take the work into his own hands. It is hypocrisy to say we love God's commandments more than our worldly interests. The way of sin is a false way, being directly contrary to God's precepts, which are right: those that love and esteem God's law, hate sin, and will not be reconciled to it.

127, 128. Therefore—that is, In view of these benefits, or, Because of the glory of Thy law, so much praised in the previous parts of the Psalm.

I love … [and] Therefore (repeated)—All its precepts, on all subjects, are estimable for their purity, and lead one imbued with their spirit to hate all evil (Ps 19:10). The Word of God admits of no eclecticism; its least title is perfect (Ps 12:6; Mt 5:17-19).
