The words, “Thanks be to God for his indescribable gift!,” are words about Jesus, God’s only Son. God is the first giver. He first gives selflessly to us in the person of His Son, Jesus Christ, true God in human flesh. The Concordia Self-Study Bible footnote says, “ . . . and all true Christian giving is our response of gratitude for this gift that is beyond description (cf. 8:9; 1 John 4:9-11).”
God’s gifts are indescribable. The gift of His Son leads us to the question, “would we give our life for someone else’s life?” We would probably answer that question with a “no,” or at best with a qualified “maybe.” God’s love for us is shown in the giving of His one and only Son, the giving of His life for ours in the most horrid of death.
Our giving pales in comparison to God’s giving and our giving is only in response to God’s giving. God gives and then He moves in us through His means of grace to respond to His giving. God is the prime mover. God is the prime giver.
Along with Paul we say, “Thanks be to God for his indescribable gift!” To God be the glory.
