If there is only one God, and the only one God is the Father
who is the Father of Christ and of His followers, and the God of Christ and His followers
, then there is no God besides Him
, nor there was formed before Him nor there will be after Him
, and that there's no other God like Him
; doesn't it mean, God knows other God besides Him?
Answer: God doesn't know not even one.
8 Do not fear, nor be afraid;
Have I not told you from that time, and declared it?
You are My witnesses.
Is there a God besides Me?
Indeed there is no other Rock;
I know not one.’”
Isaiah 44:8, NKJV
