“Then Peter started speaking: ‘I now truly understand that God does not show favoritism in dealing with people, but in every nation the person who fears him and does what is right is welcomed before him.'”
Peter finally began to get the idea of what God desired as he stood before Cornelius and his family. He speaks of Christ, vv. 37-43, but he begins by what God wants from us in order to draw near to him.
Never hesitate to put what God requires of man up front in your message to others. It’s as much a part of the gospel as the death of Christ. Make redemption clear, by sharing God’s part and man’s as well.
