John 6:60-65
We learn from these verses that some of Christ’s sayings seem hard to flesh and blood. We are told that “many” who had followed our Lord for a season, were offended when He spoke of “eating His flesh and drinking His blood.” They murmured and said, “This is an hard saying: who can hear it?”
Murmurs and complaints of this kind are very common. It must never surprise us to hear them. They have been, they are, they will be as long as the world stands. To some Christ’s sayings appear hard to understand. To others, as in the present case, they appear hard to believe, and harder still to obey. It is just one of the many ways in which the natural corruption of man shows itself. So long as the heart is naturally proud, worldly, unbelieving, and fond of self-indulgence, if not of sin, so long there will never be wanting people who will say of Christian doctrines and precepts, “These are hard sayings: who can hear them?”
