People unite over various causes. Some of those causes are righteous, while others are not. Unity based upon a righteous cause pleases the Lord and leads to righteous acts. Unity based upon ungodly or carnal causes grieves the Lord and leads to the wickedness we find so prevalent in the world today. After the flood, the Lord commanded Noah and his family to “replenish the earth” (Genesis 9:1). They could not replenish the earth if they remained together so the Lord wanted Noah’s family to spread out across the earth. Yet, the people immediately began settling together and “Noah began to be an husbandman” (Genesis 9:20). This may seem insignificant, but it was only the precursor to the unified desire in Genesis 11:4 to build “a tower, whose top may reach unto heaven.” Noah’s disobedience led to further and greater disobedience and unity in a common wicked cause.
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.
