He Came To Preach the Gospel.

Luke 4:42-44 (ESV)
And when it was day, he departed and went into a desolate place. And the people sought him and came to him, and would have kept him from leaving them, [43] but he said to them, "I must preach the good news of the kingdom of God to the other towns as well; for I was sent for this purpose." [44] And he was preaching in the synagogues of Judea.

I don’t know why, and I will have to think on it hard before I turn it into anything worthwhile, but I think Paul was echoing this statement of Jesus when he said he did not come to baptize but to preach the gospel.
Jesus puts priority on preaching the gospel over that of healing sick. Our human nature is at odds with that. We think our worldly problems are the most pressing. And far from ignoring those Jesus addresses them. But healing a few sick people, even a few hundred, doesn’t really address the real issue. All of these people die at some other point in life.
Jesus comes to preach the good news. This is more pressing, more important. With this he addresses the underlying problem. With faith we receive the kingdom of God, and eternal life, and faith comes from hearing the gospel, the good news of the kingdom of God. He needs to address this first and foremost. With that comes victory over this world of tribulation and pain, even as we endure it.
