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 s…
"A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh."
Ellen White directly references Ezekiel 36:26 in this passage.
"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. DA 407.2"
"And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead."
Ellen White directly references Luke 16:31 in this passage.
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 Sadducees.” 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 the…
"And he sighed deeply in his spirit, and saith, Why doth this generation seek after a sign? verily I say unto you, There shall no sign be given unto this generation."
The EGW passage directly references and expands upon the event described in Mark 8:12, including the detail of Jesus sighing deeply.
"Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees."
The EGW passage quotes directly from Matthew 16:6, making it a clear explicit allusion.
