That would be incorrect. The author wishes to convey that the Omniscient One perceives the deepest stirrings of the heart, our most profound emotions. David, in another place, prays, "kindle my innermost being" (Ps. 25:2). Undoubtedly, St. Subbot is not asking for fire from heaven to fall within his body; rather, he seeks a mystical baptism of flame to purify his feelings, analogous to how fire refines gold. The apostle exhorts us to don the garment of compassion (Colossians 3:12), which includes humility, gentleness, and patience.
So, what does the term innermost being signify? It represents the inception of one’s inner life, a vessel that receives spiritual nourishment; in other words, it is akin to the womb where the inner self is nurtured and matured. It embodies the conscience, which safeguards and reveals God’s law to us, and this inner sense, our spiritual guide and priest, tormented David until the night. Notice, too, that the prophet engaged in a devout practice during the night; he dedicated that time to repentance, washing his bed with tears each night (Psalms 6:7). He also instructed others that the night was a moment for spiritual reflection: "Speak in your hearts, upon your beds be still" (Psalm 4:5). The faithful generally distinguish night from day for spiritual endeavors. Thus, when the tranquility of night arrived, they immersed themselves in contemplation, reflecting on their transgressions, and in the solitude and silence, with only God’s testimony, they wept bitterly over them. They also recalled the blessings bestowed upon them that day, expressing tears of repentance alongside tears of gratitude before God. However, David did not wait for nightfall to give thanks or seek repentance from the Lord; even in the daylight, the stirring of his conscience compelled him, inciting him either to repent or to express gratitude.
This inner conscience pressed upon him forcefully, almost as if inflicting invisible blows, which manifested in physical afflictions. I believe this is the reason the prophet used the word innermost being, demonstrating that the influence of spiritual awareness does not remain confined to the spirit but resonates throughout the entire physical being. Thus, a person may groan like a wounded lion, and their tears may flow abundantly, resulting in the trembling of their very bones, for it is stated, "There is no peace in my bones" (Psalm 37:4). Anyone who strives to cleanse their conscience through adherence to the Gospel knows that this internal chastisement is closely tied to a deep sense of illness: after committing sin, they feel a turmoil within; both warmth and cold arise in their body as if a fire is lighted in their innermost being, making them ready to bear wounds (Psalm 37:18) to quench this burning. This inner torment begins to chastise even before nighttime and compels the righteous to address their sins without delay; immediately after wrongdoing, the voice of their conscience starts to chastise them.
Conversely, the holy prophet intended to express that his inner sense pursued him until night, meaning until he could finally disengage from worldly distractions and concerns to find rest. Here, upon reconciling with himself, he recognized his failings and washed them with tears of repentance. This brought peace to his soul, as his heart was cleansed through tears, thereby reconciling his conscience with God. Such an interpretation closely aligns with the preceding sentiments, especially as David praises the Lord for His guidance while illustrating the potency and constancy of divine instruction. Hence, the truly devout do not procrastinate in repentance; if they stumble, they promptly heed the call to correction. If a Christian wrongs another, they quickly seek reconciliation, as it is burdensome and destructive to harbor the painful reality of sin. Whether they stray from any other divine command, they promptly cleanse their misdeed with tears and heartfelt sighs to the Lord: "Let not the sun go down on your wrath" (Eph. 4:26). The apostle’s admonition concerning anger applies to any emotion contrary to love and the purity of the Gospel. Do not postpone your efforts to eradicate sin until nighttime or a period of rest. Given the passage of time, the sin may root itself deeper within your heart, making it increasingly challenging to remove. This concept ties in with the words of the holy prophet, "Blessed is he that taketh and dasheth thy little ones against the stones" (Psalm 136:9). When nighttime arrives, unleash your emotions—allow your tears and sighs to flow freely. During that time, nothing can obstruct your communion with God; external distractions will not diminish your sacrifice. Through this offering, your sins will be cleansed, and the Lord will reconcile with you, granting your heart the comfort fully available in the sacrament of repentance. Do not delay your expression of gratitude; kneel before the gracious God immediately, and once the moment of comfort arrives, offer a prayer of thanksgiving in humility. Finally, as St. Peter the Apostle explained, this Psalm points to the Saviour (Acts 11:27, 31). The phrase, "Yet even unto the night have my innermost being chastised me," beautifully encapsulates this profound understanding of David’s Song. In it, the Redeemer in human form glorifies God for His wisdom. The fact that the Redeemer, as man, was instructed by the divine is evident in several passages from the Holy Gospel. He declared, "I can do nothing of my own accord; as I hear, I judge" (John 5:30). "For the Father loves the Son, and shows Him all things that He Himself does; and greater works than these will He show Him, so that you may marvel" (John 5:20). Furthermore, He stated, "As the Father commanded Me, so I do" (John 14:31). Subsequently, He turns to His innermost feelings, indicating that His inner compulsion to fulfill the mission of redeeming humanity persisted; the Evangelist often affirms that Jesus was moved with compassion for the shepherdless multitudes, grieved by the obstinacy of the hard-hearted Pharisees, and anxious to participate in one last Passover with His disciples to complete the work of salvation: "I have earnestly desired to eat this Passover with you before I suffer" (Luke 22:15). This profound compassion for sinners did not leave Him even until night; it drove Him until that hour when Judas decided to betray Him. "It was night," the Evangelist notes, "when Judas went out to betray the Lord" (Jer. 8, p. 45. John 13:30. Theodoret’s commentary). According to this interpretation, the Psalmist’s words impart a timely lesson: if you sense an urge toward goodness in your heart, if you hear a call inviting you to pursue Christian action, do not stifle it through distraction, nor diminish it through neglect, but allow it the freedom to resonate within your soul until you fulfill its call to the best of your ability.
