Now consider what follows: “Blessed are those who keep His testimonies and seek Him with all their heart” (Psalm 117:2). It seems evident that the only group of the blessed referenced here is the one we’ve just analyzed. To study the testimonies of the Lord and to seek Him wholeheartedly is indeed to be blameless on the path; it is to follow the law of the Lord. Then it is stated, “For those who do evil shall not walk in His ways” (Psalm 118:3). Yet we are aware that those who commit wrongdoing often examine the testimonies of the Lord, as they prefer understanding over righteousness; we know that others study these testimonies not because they are already living righteously, but to learn how they ought to live. Such individuals do not yet walk blamelessly in the law of the Lord, and consequently they are not yet blessed...
It is recorded in this psalm, and stands true: “those who do evil do not walk in His ways” (Psalm 118:3). We must strive, with God’s assistance, in whose hands we and our words reside (Wisdom 7:16), that which is rightly stated is not misunderstood by the reader or listener. We should take care lest all the saints, whose words reflect, “If we say that we have no sin, we deceive ourselves, and the truth is not in us” (1 John 1:8-9), be thought unable to walk in the paths of the Lord, since sin is wrongful, and those who do evil do not stroll in His ways. Or, since it is clear that they walk in the paths of the Lord, may they be presumed to have no sin, which is certainly untrue. This is not expressed merely to prevent pride and arrogance; otherwise, it would have been stated, “Humility is not in us.” Furthermore, the subsequent words clarify the meaning and remove any grounds for doubt. After asserting this, the blessed John adds, “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 mean: “You have accused us of keeping Your commandments too strictly”? (Psalm 118:4). Did you demand too large a sum? Or did you leave us lacking? Whichever interpretation we adopt seems contrary to that wise and esteemed notion praised by the Greeks in their philosophers and hailed by the Latins: “Do nothing in excess.” The Latin tongue sometimes employs the term “nimis” in such a way that it is found in scripture and used in our conversations as very significant. When you declare, “You have accused us of keeping your commandments too much,” we glean great meaning if we interpret it correctly; when one tells a cherished friend, “I love you too much,” it does not imply excessive expression, but rather profound affection.
Oh, if only, he states, my ways would be made straight so that I might follow Your decrees (Psalm 118:5). You have indeed taken upon Yourself a weighty matter: oh, if I could perceive what You have taken upon Yourself. When you hear this, recognize the intentions behind the words; and as you grasp this expression of desire, cast aside the arrogance of presumption. For who proclaims that they long for what lies within their reach to accomplish by themselves? Therefore, if one yearns for what God commands, he should earnestly pray that God enables him to fulfill those commandments...
And I shall not be put to shame as long as I observe all Your commandments (Psalm 118:6). We ought to regard God’s commandments when they are read or recalled, as one might view a mirror, as the apostle James instructs (James 1:23-25). This individual wishes to see himself clearly, so that he can examine the commandments of God without confusion; he chooses to be not only a listener to them but a practitioner. Thus, he desires his paths to be straightened and to uphold the statutes of God. How can one achieve a straight path if not through God's grace? Otherwise, he will discover in the law of God not a source of joy but of disarray, if he attempts to reflect upon commandments he does not keep.
“I will confess to You, O Lord, with the guidance of my heart; in this, I shall understand the judgments of Your righteousness” (Psalm 117:7). This is not a confession of transgressions, but one of commendation; just as He stated, “I confess to You, O Father, Lord of heaven and earth” (Matthew 11:25), and as it is articulated in Ecclesiasticus, “So declare all the works of God that they are exceedingly good” (Sirach 39:15-16). I confess to You, he asserts, in accordance with my heart's direction. Indeed, if my ways are aligned correctly, I will confess to You, for it is You who has accomplished it; this is Your praise and not my own...
He then states, “I will observe Your decrees” (Psalm 118:8)... But what follows? “O leave me not even too much!” Or, as some manuscripts assert, “Even too much, do not leave me!” Given that God forsook the world in its wilderness of sins, He could have abandoned it in greater measure had it not been upheld by a robust remedy—namely, by the grace of God through our Lord Jesus Christ; nonetheless, in response to this prayer from the body of Christ, He has not forsaken it at all.
