"He remembers his covenant forever, the promise he made for a thousand generations." (Psalm 105:8)
Psalm 105 is one of the great historical psalms, a sustained narration of God's faithfulness from the covenant with Abraham through the Exodus and the entry into Canaan. Its opening call, give praise to the LORD, proclaim his name, tell of all his wonderful acts, is a missionary call to make the acts of God known among the nations. Memory in the service of proclamation: this is what the psalm models. And the foundation of all the subsequent narration is a single verse: He remembers his covenant forever, the promise he made for a thousand generations, the covenant he made with Abraham, the oath he swore to Isaac.
God's faithfulness in this psalm is the faithfulness of one who remembers. He remembered his holy promise, and Abraham his servant. He brought out his people with rejoicing, his chosen ones with shouts of joy. The plagues of Egypt, the pillar of cloud, the quail and the bread from heaven, the water from the rock: all are presented as acts of the God who remembers his word and will not let it fail. The Catechism presents the covenant as the master key to the whole of biblical history: God is always the initiating party, always the faithful one, always the one who remembers even when his people forget (CCC 2569).
Brothers and sisters, your Baptism is a covenant God made with you, as real as the one he made with Abraham. He remembers it even when you have forgotten it. He has not revoked it. He has not moved on. He is the God who remembers for a thousand generations. What would change in how you live if you truly believed that the God of Psalm 105 remembers the covenant he made with you?
Lord God, you remember your covenant forever and the promise you made for a thousand generations. You remembered Abraham, you remembered Israel, you remember us. Let us never forget what you have remembered, and let our lives be a proclamation of your wonderful acts. Through Christ our Lord. Amen.
