Paul's account of being caught up to the third heaven fourteen years earlier demonstrates divine revelation's reality while maintaining appropriate humility about mystical experiences that cannot be shared. His teaching about the thorn in the flesh reveals how God's grace proves sufficient for every weakness, with divine strength perfecting itself through human limitations rather than impressive capabilities. The signs, wonders, and miracles performed among the Corinthians authenticate his apostolic ministry while his refusal to burden them financially demonstrates love that seeks their benefit rather than personal advantage.
