David answers to the words of the Lord in a way that we should learn and imitate.
He is full of gratitude, he asks the Lord to confirm his promise and to bless his kingdom.
David understands the words of God as a covenant, the solid foundation of his hope.
We too receive everyday Jesus as the gift of the Father in Heaven. We need to be thankful and assured that the Lord is fulfilling his promise to us, even if sometimes we do not see clearly.
