In Science and Health Mary Baker Eddy wrote, "Every day makes its demands upon us for higher proofs rather than professions of Christian power. These proofs consist solely in the destruction of sin, sickness, and death by the power of Spirit, as Jesus destroyed them. This is an element of progress, and progress is the law of God, whose law demands of us only what we can certainly fulfil" (p. 233).
This passage seems to be saying that if we are presented with death, then God's law supplies us what we need to eliminate it. However, the Apostle Paul stated, "The last enemy that shall be destroyed is death" (I Cor. 15:26).
According to the Gospel of John, Jesus raised Lazarus at the end of his ministry on earth. Was Jesus presented with Lazarus' death only at the time of his career when he could "certainly fulfil" the demand to raise him from death? Must we, too, demonstrate a lot of healing works before being able to raise the dead?
