New Testament theology begins in the Old, where God is revealed as the heavenly sovereign who faithfully loves his people and his earthly realm. So when the OT uses phrases that are crucial to Christian theology, they’re the seeds of what God was planting. The OT provides another dimension of insight into what those phrases mean for us.
Four of those phrases turn up on the lips of the messiah in Psalm 145. We’ve seen how the Davidic king announced the kingdom of God (145:1–8) and extended it beyond Israel to all people (145:9–16). Then he makes four statements about the character of God, statements that brilliantly illuminate the theology (words about God) in the Gospels and apostolic letters:
- the righteousness of God (verse 17)
- calling on the Lord in truth (verse 18)
- salvation (verse 19)
