The highest evidence that He came from God is that His life revealed the character of God. He did the works and spoke the words of God. Such a life is the greatest of all miracles.
When the message of truth is presented in our day, there are many who, like the Jews, cry, Show us a sign. Work us a miracle. Christ wrought no miracle at the demand of the Pharisees. He wrought no miracle in the wilderness in answer to Satan's insinuations. He does not impart to us power to vindicate ourselves or to satisfy the demands of unbelief and pride. But the gospel is not without a sign of its divine origin. Is it not a miracle that we can break from the bondage of Satan? Enmity against Satan is not natural to the human heart; it is implanted by the grace of God. When one who has been controlled by a stubborn, wayward will is set free, and yields himself wholeheartedly to the drawing of God's heavenly agencies, a miracle is wrought; so also when a man who has been under strong delusion comes to understand moral truth. Every time a soul is converted, and learns to love God and keep His commandments, the promise of God is fulfilled, "A new heart also will I give you, and a new spirit will I put within you." Ezek. 36:26.
The change in human hearts, the transformation of human characters, is a miracle that reveals an ever-living Saviour, working to rescue souls. Aconsistent life in Christ is a great miracle. In the preaching of the word of God, the sign that should be manifest now and always is the presence of the Holy Spirit, to make the word a regenerating power to those that hear.
This is God's witness before the world to the divine mission of His Son.
Those who desired a sign from Jesus had so hardened their hearts in unbelief that they did not discern in His character the likeness of God. They would not see that His mission was in fulfillment of the Scriptures. In the parable of the rich man and Lazarus, Jesus said to the Pharisees, "If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead." Luke 16:31. No sign that could be given in heaven or earth would benefit them.
Jesus "sighed deeply in His spirit," and, turning from the group of cavilers, re-entered the boat with His disciples. In sorrowful silence they again crossed the lake. They did not, however, return to the place they had left, but directed their course toward Bethsaida, near where the five thousand had been fed. Upon reaching the farther side, Jesus said, "Take heed and beware of the leaven of the Pharisees and of the 408Sadducees." The Jews had been accustomed since the days of Moses to put away leaven from their houses at the Passover season, and they had thus been taught to regard it as a type of sin. Yet the disciples failed to understand Jesus. In their sudden departure from Magdala they had forgotten to take bread, and they had with them only one loaf. To this circumstance they understood Christ to refer, warning them not to buy bread of a Pharisee or a Sadducee. Their lack of faith and spiritual insight had often led them to similar misconception of His words. Now Jesus reproved them for thinking that He who had fed thousands with a few fishes and barley loaves could in that solemn warning have referred merely to temporal food. There was danger that the crafty reasoning of the Pharisees and the Sadducees would leaven His disciples with unbelief, causing them to think lightly of the works of Christ.
The disciples were inclined to think that their Master should have granted the demand for a sign in the heavens. They believed that He was fully able to do this, and that such a sign would put His enemies to silence. They did not discern the hypocrisy of these cavilers.
