Remember: ➛ Jesus is the eternal Word in flesh Joh 1:14 and ➛ the Word is inseparable from the Holy Spirit Joh 1:1.
If all power in heaven and earth belongs to Christ Jesus there is no power or authority left for any other being in the universe. This means that He and He alone is ➛ Mighty God ➛ Everlasting Father ➛ Saviour ➛ Lord ➛ King Isa 9:6.
This verse speaks to the singleness of God as manifested in Christ Jesus. In the next verse Jesus tells us to teach and baptize people in His name as He is the Father, the Son and the Holy Spirit.
