Next, consider his words: “Blessed are they that keep his testimonies and seek him with all their heart” (Psalm 117:2). It appears that no other group of the blessed is referenced here other than what has already been discussed. To explore the testimonies of the Lord and to earnestly pursue Him is to embody blamelessness on the path; it signifies walking in the law of the Lord. He also declares, “For they that do evil shall not walk in His ways” (Psalm 118:3). Nonetheless, it is evident that those who commit wickedness do examine the testimonies of the Lord, motivated more by a desire for knowledge than righteousness; some study the testimonies not because of their virtuous living but to discover how they ought to conduct themselves. Such individuals do not yet walk blamelessly in the law of the Lord, and thus they have not yet received the blessedness...
It is affirmed in this Psalm: “They that do evil do not walk in His ways” (Psalm 118:3). Yet, we must strive, with God's aid, who holds our words and us in His hands (Wisdom 7:16), that what is said correctly is also interpreted accurately, so the reader or listener is not led into confusion. We must guard against the notion that all saints who declare, “If we say we have no sin, we deceive ourselves, and the truth is not in us” (1 John 1:8-9), do not indeed walk in the paths of the Lord, since sin is wrong and those who do wrong do not follow His ways; or, since they undoubtedly walk in those ways, they might mistakenly be thought to be sinless—a notion that is certainly erroneous. This was expressed not just to avoid vanity. Otherwise, it would not have added, "And the truth is not in us," but would have stated, "Humility is not in us," especially as the subsequent words clarify the meaning and eliminate any uncertainty. For after stating this, blessed John continues, “If we confess our sins, He, being faithful and just, will forgive us our sins and cleanse us from all unrighteousness” (1 John 1:9)...
What does it imply when it says: “You have accused us of keeping Your commandments too strictly” (Psalm 118:4)? Have You demanded too great a price? Or have we given too much? Whatever these questions suggest, the meaning seems contrary to the lofty and noble wisdom praised by Greek sages, as well as the consensus of the Latins, which is to avoid excess. However, the Latin language sometimes employs the term “nimis” in ways that resonate deeply, as we find in Scripture and use meaningfully in conversation. In this instance, “You have accused us of keeping Your commandments too much” suggests a profound understanding; when we express love for a cherished friend as “I love you too much,” we do not imply an excess beyond propriety, but rather a considerable depth of feeling.
Oh, if only, he laments, “my ways would be so directed that I might keep your decrees” (Psalm 118:5). You have indeed accepted the burden. Consider what you have taken upon yourself. When you hear this, recognize the words of one who is willing; having identified this desire, cast aside the arrogance of presumption. For who among us can truly desire what lies within our ability to achieve unaided? Thus, if one longs for what God commands, one must earnestly pray to Him for the grace to fulfill those commands...
“I will not be put to shame as long as I keep all Your commandments” (Psalm 118:6). When we encounter God’s commandments in reading or recollection, we should regard them as a mirror, as the apostle James states (James 1:23-25). This person aspires to perceive the commandments of God in such a way that they are not dismayed, choosing to be not merely hearers, but doers. Hence, he longs for his paths to be straight so he can observe God's statutes. How can one attain this straightness, if not by God’s grace? Otherwise, in contemplating God's law, one would find not joy but confusion, especially if one intends to scrutinize commandments that remain unobserved.
“I will confess to You, O Lord, with a pure heart; in this I shall understand the judgments of Your righteousness” (Psalm 117:7). This confession is not one of sins, but of worship; as it is articulated, “In whom there is no sin, I confess to You, O Father, Lord of heaven and earth” (Matthew 11:25) and also as recorded in Ecclesiasticus: “So acknowledge all the works of God that they are very good” (Sirach 39:15-16). “I confess to You,” he states, “with the guidance of my heart.” Indeed, if my ways are made upright, I shall confess to You because it is Your work, and it is Your praise—not mine...
Furthermore, he declares, “I will keep Your decrees” (Psalm 118:8)... And yet what follows? “Do not forsake me even too much,” or as some versions say, “Not even excessively.” But since God has not utterly abandoned the world amidst its sins, He surely would have withdrawn entirely, had it not been supported by such a powerful remedy, namely, the grace of God through our Lord Jesus Christ; but now, according to Christ's body’s prayer, He has not forsaken it even excessively, for God was in Christ reconciling the world to Himself (2 Corinthians 5:19)...
