Christianity

In this Psalm the gentiles are invited to join in praise of God. Christians would view this as a fulfillment of God's promise of mercy to the gentiles, pointing to God's promise that all nations would be blessed in the seed of Abraham whom they believe is Christ, as described in the book of Galatians. Galatians 3:16 says "The promises were spoken to Abraham and to his seed. The Scripture does not say "and to seeds," meaning many people, but "and to your seed," meaning one person, who is Christ."
