The Spirit who dwells in Jesus Christ is the Father (John 4:23-24, John 14:7-11).
There is one Lord in holy scripture (Ephesians 4:5, Mark 12:29 (kjv)), and that Lord is the Father (Matthew 11:25, Luke 10:21).
No one can say that Jesus is the Lord except by the Spirit of truth (1 Corinthians 12:3 (kjv)).
And, Jesus is the one Lord (1 Corinthians 8:6).
If Jesus and the Father are not one, that is two Lords; a concept that is contrary to holy scripture (mark 12:29 (kjv), 1 Corinthians 8:6, Ephesians 4:5).
