The healed man tells the critics that Jesus had made him whole, or healed him, dismissing their question about who had told him to carry the bed. The Jewish critics had emphasized his carrying the bed, but the healed man (after Christ's revelation of Himself to him) put the emphasis on the Healer, suggesting which was more important. The spiritual priority was the healing, the work of Christ.
When people criticize God the Father, His Son Jesus Christ, and the church, it is often because they have trouble recognizing what is truly important. Ignoring God's grace and mercy, they instead focus on a supposed violation of law, usually one they have perverted or made up, as the Pharisees did. They attack the Word of God, ignoring its important messages, and focus on picky, alleged discrepancies or fine points of the letter of the law. We must have the right priorities clearly in our minds if we are to serve and revere the sovereign God acceptably and diligently.
