Matthew 11:6

6.And blessed is he who shall not be offended in me. By this concluding statement Christ intended to remind them, that he who would adhere firmly and steadfastly to the faith of the Gospel must encounter offenses, which will tend to interrupt the progress of faith. This is said by way of anticipation, to fortify us against offenses; for we shall never want reasons for rejecting it, until our minds are raised above every offense. The first lesson, therefore, to be learned is, that we must contend with offenses, if we would continue in the faith of Christ; for Christ himself is justly denominated a

rock of offense and stone of stumbling, by which many fall,
(1 Peter 2:8.)

This happens, no doubt, through our own fault, but that very fault is remedied, when he pronounces those to be blessed who shall not be offended in him; from which too we infer, that unbelievers have no excuse, though they plead the existence of innumerable offenses. For what hinders them from coming to Christ? Or what drives them to revolt from Christ? It is because he appears with his cross, disfigured and despised, and exposed to the reproaches of the world; because he calls us to share in his afflictions; because his glory and majesty, being spiritual, are despised by the world; and in a word, because his doctrine is totally at variance with our senses. Again, it is because, through the stratagems of Satan, many disturbances arise, with the view of slandering and rendering hateful the name of Christ and the Gospel; and because every one, as if on purpose, rears up a mass ofoffenses, being instigated by not less malignity than zeal to withdraw from Christ.
