Cornelius and then Peter are now redirected by God. One by a voice the other by a vision, the vision being confirmed later by the voice. Notice that the meaning of the vision is still unknown to Peter and Cornelius certainly doesn't even know about it either. God produced a desire to pursue an eventual answer, created a means outside of Peters own construction to deliver it, and is insisting first and foremost on the trust and obedience of both men to reach the further knowledge.
