God’s action in the Old Testament revealed His omnipotence—His divine power—and proved that He is always faithful to His people.
In the Old Testament, God’s people learned the truth of His almighty power in Creation.
This reminded the people that God always remains with His people to protect and help them. His powerful and victorious deeds show that He keeps His promises and that He loves His people.
After speaking through the Old Testament prophets, God the Father sent our Savior, Jesus Christ, Who is God the Son made man. Being both God and man, Jesus gave us the “Good News” of Salvation. This message is found in the New Testament. By His words and actions, Jesus made known the deepest truths about God. The Blessed Trinity (Father, Son, and Holy Spirit) is the deepest of all these truths.
