"Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit (Matthew 28:19 NKJV)"
"Now when all the people were baptized, Jesus was also baptized, and while He was praying, heaven was opened, and the Holy Spirit descended upon Him in bodily form like a dove, and a voice came out of heaven (from God the Father), 'You are My beloved Son, in You I am well-pleased' (Luke 3:21-22 NASB)."
