Burden-of-proof moment: Actually, it hasn't been proven yet that the Bible is divinely inspired, so anyone who wants to claim that needs to bring their strongest logic boots and start climbing.
And yes, Jesus said (according to the account of the gospels, ie things written at least 30 years after his death), "Blessed are those who have not seen, and have yet believed." (John 20:29), and “"For the Kingdom of God belongs to those who are like these children. I tell you the truth, anyone who doesn’t receive the Kingdom of God like a child will never enter it.” (Mark 10:14-15), but he comes out of the tradition of Midrashing scripture, and Paul caps this notion of childlike faith with "When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me." (Corinthians 13:11)
