It isn’t in your Bible? Dude, get some better teaching!
God is EXPLICITLY said to be one; the Father is EXPLICITLY said to be God, the Son is EXPLICITLY said to be God; the Spirit is EXPLICITLY said to be God.
That’s the Trinity.
Bad, bad analogy!
God promised to bless all nations through Abraham.
That promise unfolded throughout all of Scripture. That’s the above in a nutshell.
