Jesus was faithful. Jesus remains faithful. Jesus will be faithful. This theme of faithfulness is the foundation of Paul's view of how God intends to save the world through sending his Son. To see the the faithfulness of Jesus in the New Testament requires a proper understanding of the big story the Bible is telling, a four-act story of Creation, Corruption, Covenant, and New Creation. With that story in mind, we can see the faithfulness of Jesus in Paul's description of the death of Jesus in Romans 3:21-24. Through his faithfulness, God declares us justified, and thus incorporated into the covenant people of God.
