The Apostle Paul: Is it true Paul tried to preach in his own prowess at first, just trying to be intellectual, his own knowledge, but wasn't spirit-filled, & came out of Athens sort've deflated, but that in 1 Corinthians 2, he completely changed his approach to how he preached, to preach Jesus & Him crucified only? Is this true? [Acts 17, 1 Corinthians 2:2] Paul after his conversion: Was Paul in seclusion from preaching after his conversion in Damascus for several years? [Galatians 1:15-24, 2:1]
