“Let us now ask ourselves why God seeks men’s thanks. Why did He seek of Noah, Moses, Abraham and other of our forefathers that they offer Him sacrifices of thanksgiving (Genesis 8:20-21; 12:7-8; 35:1; Leviticus Ch. 3)?
Why did the Lord Jesus every day give an example to the world of how we must give thanks to God (Matthew 11:25; 14:19; 26:26-7)? Why did the apostles do the same (Acts 2:47; 27:35), commanding all the faithful to give thanks to God in and for all things (Ephesians 5:20; Colossians 3:17)? Do we find great Isaiah’s words incomprehensible: “I will mention the lovingkindness of the Lord, and the praises of the Lord, according to all that the Lord hath bestowed on us, and the great goodness” (Isaiah 63:7)? Or what the gentle Psalmist advises his own soul: “Praise the Lord, O my soul, and forget not all His benefits” (Psalm 102/103:2)? Why, then, does God seek men’s thanks? It is out of His endless love for mankind that God seeks that men give Him thanks. The thanks of men will not make God greater, more powerful, more glorious, richer or more alive, but they will make men all of those things.
Man’s gratitude will not add anything to God’s peace and contentment, but it will add greatly to man’s. Thanksgiving to God will in no way change God’s state and being, but it will change these in a grateful man. God has no need of our gratitude, nor are our prayers necessary to Him. But is this same Lord who said: “Your Father knoweth what things ye have need of, before ye ask him.” (Matthew 6:8) who at the same time recommended that men ought always to pray, and not to faint (Luke 18:1). God may not feel the need of our prayers, but He nevertheless demands it of us – the thanksgiving that is nothing other than a form of prayer – a prayer of thanksgiving.
Thanksgiving to God raises us mortals out of the corruption of mortality, releases us from that from which we must all at some time be released, whether we will or not, and binds us to God the living and immortal; if we are not bound to Him in this life, then we shall never be in His presence in eternity. Thanksgiving ennobles the thankful and nourishes good works. Thanksgiving inspires benevolence in the world and gives freshness to every virtue.” (St Nikolai Velimirovic, Homilies, p. 300)
