Mark 3:7-12 is a summary of the ministry of Jesus Christ to this point in the Book of Mark. On the surface, it seems like a very simple message, one I was tempted to skim over and bundle together with the next verses in chapter three on the calling of the disciples. However, I am glad that the Lord led me to stay with the text and push through. There are reminders here that our small church plant can use even though we have already studied some of these concepts.
In these verses we see Jesus drawing a huge crowd. The crowd was so large that Jesus was in danger of being crushed by it. They came from every region throughout Palestine. Well, almost every region. One is conspicuous by its absence--Samaria. Here we see the missionary heart of our Lord. People came from extreme distances to see His ministry, but those that did not come from Samaria would be reached by Him in John 4. Jesus had a divine appointment with a woman at a well. Those that did not seek out Jesus would be sought out by Him.
We also see a summary of Jesus' miraculous ministry. He healed, "promiscuously." "Many" came to them and He healed them "all". Why? Because they deserved it? No. He healed them because He is a God of grace; He gives undeserved favor to those who only deserve Hell. Since He is the same yesterday, today and forever we can rest in His compassion and grace to us and those we love when they are sick. We can lift them up in prayer because there is provision for healing in the atonement (Isaiah 53:4-5; cf. Matt. 8:16-17). We don't take people to Benny Hinn or any other so-called "faith-healer." The Lord Jesus is able to heal directly, without the aid of a mediator. Sometimes, He uses the medical profession in that healing process.
He also exercised spiritual authority over the demons. In other passages He casts them out. No exorcisms are mentioned here in Mark. We do learn a couple of lessons from this authority. First, there is a demonic faith (cf. Jas. 2:19-20). Second, the Lord cares about the messenger and not just the message. He did not want demon possessed people proclaiming truth and He does not want unqualified men preaching in pulpits.
