How do you know only one God and Jesus is true? What’s the proof
The Bible, meaning the Old Testament (which is from the Jews) and the New Testament (which is also from the Jews). Read it and test it for yourself. That’s how I settled the matter for myself about whether there was one God or not, Jesus or not, what was true or not and what was the proof.
You can read it yourself and find these things out.
Yeah, You provide a way to know God,
Read the Bible and test it for myself.
Because Bible said，Isaiah 44:6
“This is what the Lord says - Israel 's King and Redeemer, the Lord Alimighty: I am the first and Iam the last, apart from me there is no God”
Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me.
