Mark 9:20
. And as soon as he saw him. That the devil should rage with more than ordinary cruelty against the man, when he is brought to Christ, ought not to excite surprise; for in proportion as the grace of Christ is seen to be nearer at hand, and acts more powerfully, the fury of Satan is the more highly excited. The presence of Christ awakens him like the sound of a trumpet. He raises as violent a storm as he can, and contends with all his might. We ought to be prepared beforehand with such meditations, that our faith may not be disturbed, when the approach of the grace of Christ is met by more than ordinary violence on the part of our enemy. Nor ought we to lose sight of another point, that the true commencement of our cure is, when our affliction is so heavy that we are almost at the point of death. It must also be taken into account that, by means of the furious attack of Satan, our Lord lights a torch to cause his grace to be seen; for, when the spectators were appalled at the dreadful spectacle, the display of the power of Christ, which immediately followed, was more distinctly perceived.
