In several of Paul's letters he expresses the greeting, "Grace to you and peace from God our Father and the Lord Jesus Christ" (Eph 1:2) representing two members of the three-person Deity. "God created the heavens and the earth" (Ge 1:1) and "the Spirit of God was moving over the surface of the waters" (:2). "Then God said, 'Let Us make man in Our image'" (:26). The Father alone is not the "first cause" as Greek philosophy might argue. But Jesus was sent by the Father because he said his desire was "'to do the will of Him who sent Me, and to accomplish His work'" (Jn 4:34). Also Jesus explained that when the Holy Spirit arrives, "'He will not speak on His own initiative, but whatever He hears, He will speak'" (Jn 16:13). Then Paul explains that at the finish "comes the end, when He delivers up the kingdom to the God and Father" (1Co 15:24).
Paul told the Colossians he had "heard of your faith in Christ Jesus" (Col 1:4) that they had "heard in the word of truth, the gospel" (:5) in which they "understood the grace of God in truth" (:6). It is "the hope of the gospel that you have heard" (:23). Paul told the Romans he was "not ashamed of the gospel, for it is the power of God for salvation" (Ro 1:16) because "in it the righteousness of God is revealed from faith to faith" (:17). He was sent to "preach the gospel" (1Co 1:17) "by which you are saved" (15:2). "The word of the cross is . . . to us who are being saved . . . the power of God" (1:18). "God was in Christ reconciling the world to Himself" (2Co 5:19). They comprehended "the grace of God in truth" (Col 1:6) which means that they fully and experientially knew. Jesus "was with God, and the Word was God" (Jn 1:1) and "the Word became flesh . . . and we beheld His glory . . . full of grace and truth" (:14). Jesus prayed, "'Sanctify them in the truth; Thy word is truth'" (Jn 17:17). It is "the mystery which has been hidden from the past ages and generations; but has now been manifested" (Col 1:26) "which is Christ in you, the hope of glory" (:27).
