I have come upon some verses were Jesus refers to His Father as ‘My God’. Rev 3:12 is a Good example. Having had past experience with people who don’t believe in the trinity is a text they pounce on! “If Jesus was God”, they say, “Then how come he is calling his Father ‘My God?” What’s the best answer to that text?
God appears to us in three persons, Father, Son and Holy Spirit. The Holy Spirit doesn’t speak in Scripture, but both Father and Son refer to each other by their titles. For example, in Matt. 17:5 the Father said, “This is my son, whom I love …”, yet in Hebrews 1:8 He is quoted as calling Jesus God. On the cross Jesus cried out to “My God” and often referred to God as His Father. But throughout the New Testament, in the words of Jesus (John 10:30), John (John 1:1), and Paul (Col. 1:15-16) the fact that Jesus is God in the flesh is well documented. In short, the Biblical evidence is compelling. They are Father and Son and they are God.
