Recently my favorite chapter of the Bible has been John 14 it is an amazing chapter to defend the christian belief of the trinity!
"Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works." (John 14:10)
"Believe me that I am in the Father, and the Father in me...."
