Old testament for what it was a story and that he was here on Earth to replace those stories with his word and his law.
What Jesus and Old Testament are you talking about?
The words of Jesus
“The secret of the kingdom of God has been given to you. But to those who do not know the secret, everything remains in parables, so that, ‘seeing they may see and not perceive, and hearing they may hear and not understand; lest they should turn, and their sins be forgiven them’”.
“You hypocrites, Isaiah described you beautifully when he wrote - ‘This people honours me with their lips, but their heart is far from me. And in vain they worship me, teaching as doctrines the commandments of men’. You are so busy holding on to the traditions of men that you let go the commandment of God!”
“Humanly speaking it is impossible, but not with God. Everything is possible with God.”

“I assure you that we are talking about something we really know and we are witnessing to something we have actually observed, yet men like you will not accept our evidence. Yet if I have spoken to you about things which happen on this earth and you will not believe me, what chance is there that you will believe me if I tell you about what happens in Heaven?”
