(Synoptics: Luke 12:1-3)Having condemned the Pharisees and lawyers so forcefully for their self-righteousness and sham, the Lord next gives this warning to his disciples about their teaching. It is hypocrisy and therefore is to be completely disregarded; there is no profit in it at all.
But this leaven, Christ warns, is hypocrisy. What does that mean? It means that the poison of hypocrisy is in it and influencing it. Hypocrisy is a constituent part of their doctrine, and what it produces will show the same pattern in some form. Is hypocrisy something which is possible to teach? Yes, because man is predisposed towards it by nature. He does not want to come to God, to submit to his authority, to put away the corruption of sin. The pure doctrine of Christ purges the soul and does not allow falsehood to remain unchallenged. But the doctrine of hypocrisy makes it easy for the old nature to continue to operate, and hypocrisy which is a tendency for all who are fallen, is allowed to remain and grow. Teaching alone cannot turn a child of this world into a child of God. There must be the work of the Spirit in the heart and the new birth, and a conversion experience. But without true doctrine, the Spirit will not work, and the effect will be to produce more of the same, more men and women made in the image of Adam, and in this case of the Pharisees.
