Mar 13:32 But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
When faced with the above scripture, Trinitarians will immediately deflect and point to John 21:17:
He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
Is the Bible contradicting itself? No. The sense Peter is using it was already denoted in John 16.
29 His disciples *said, “Lo, now You are speaking plainly and are not using a figure of speech. 30 Now we know that You know all things, and have no need for anyone to question You; by this we believe that You came from God.”
Notice the apostles don’t say that his knowing of all things proves he is the creator. It proves he came from the creator; that he was taught his doctrine from the creator. John 15:15.
The same sense is given to us in 1 John 2 of those believers taught of the Holy Spirit:
20 But ye have an unction from the Holy One, and ye know all things.
Are the Trinitarians now going to tell us that the elect are the creator as well?
John 7:14 But when it was now the midst of the feast Jesus went up into the temple, and began to teach. 15 The Jews then were astonished, saying, “How has this man become learned, having never been educated?”16 So Jesus answered them and said, “My teaching is not Mine, but His who sent Me. 17 If anyone is willing to do His will, he will know of the teaching, whether it is of God or whether I speak from Myself. 18 He who speaks from himself seeks his own glory; but He who is seeking the glory of the One who sent Him, He is true, and there is no unrighteousness in Him.
