I know people & know of many others who know the Bible very well (even college professors) that don't believe in Him. Not to bring this subject into the mix, but I know of many who were Baptized who no longer believe. The only way you can believe is if the father wishes.
John 6:44 “No one can come to me unless the Father who sent me draws them, and I will raise them up at the last day.
The Bible opens our understanding of who he is . Luke 24:45
We can't come into this without the Father revealing himself to us & without the Bible to guide our path
