Not everyone is meant to agree. There is no commandment regarding a particular "what or who is God." Jesus was a Jew, who for the most part preached to other Jews. However, there are two very telling instances given in the NT Scriptures.
1) The woman at the well. A Samaritan, therefore not "acceptable" to worship in the Jewish temple. And what did Jesus say to her? John 4: 23But a time is coming and has now come when the true worshipers will worship the Father in spirit and in truth, for the Father is seeking such as these to worship Him. 24God is Spirit, and His worshipers must worship Him in spirit and in truth.” He does not tell her she needs the temple, or even that she needs to believe in him. She just needs to worship in spirit and truth--truth as she knows, apparently.
2) Then there's the story of the Roman Centurion. Did Jesus ask him to rebuke Jupiter? No. Did he ask him what God he worshipped? No. He simply took notice of the man's pure faith: Matt 8: 10When Jesus heard this, He marveled and said to those following Him, “Truly I tell you, I have not found anyone in Israel with such great faith. 11I say to you that many will come from the east and the west to share the banquet with Abraham, Isaac, and Jacob in the kingdom of heaven. Take note of that last line--MANY will come and share.
And a last note directed especially to Christians: Jesus stated in Matt 20:15 Am I not allowed to do what I choose with what belongs to me? Or do you begrudge my generosity?’
