Sin is not to be considered a light matter. In other words, it is not to be mocked. Only a fool would demonstrate this kind of behaviour toward sin.
There are two categories of sin: sins against God and sins against man. By default, every sin is against God. Yet, not all sin is against man.
Most people view sin as a private or earthy matter. Yet, every sin is against the Lord. In truth, men can sin against the Father, the Son, and the Spirit.
Sin and those who participate therein anger Lord. In the days of Noah, sin grieved the Lord so badly that it repented God that he had made man on the earth.
The Lord healed many people during His earthly ministry. Today's passage speaks of a particular man who had been delivered from devil possession. What a relief he must have experienced! However, the people in his community did not rejoice that the Lord had performed such a wonderful miracle. In fact, they turned against the Saviour and wanted Him to depart from their coasts. The Lord complied with their demands; however, the man delivered of the devils wanted to travel with the Lord. He loved the Lord so much that he wanted to stay close to Him. However, as the healed man sought to enter the ship, Christ told him to return to his home and tell his friends what had happened to him. The Lord knew that this man was in the best position to reach out to his friends with the truth. He knew this man's testimony concerning the truth was what they needed to hear and believe. Christians should always be prepared and ready for times when opportunities arise to tell their friends about the truth. Acts chapter 10 records another example when Cornelius called his friends together expecting to hear Simon Peter preach the truth of the gospel. Real friends insure that their friends are put into a position to hear the truth and never squander spiritual opportunities.
