The truth is not always pleasant

If you observe how Jesus and his apostles preached and taught
God's word, then you see that they did not appear with exaggerated
kindness or flattery. They did not try to represent the message of
salvation so pleasant as possible. No, they preached THE TRUTH
and many, specially the Pharisees and the teachers of the law,
comprehended the truth as very unpleasant, and so it has always
been. The worst enemies of the living Christianity have always
been found among the religious leaders.
