We should have those who disciple us. However we must be careful of who we entrust ourselves to. Jesus warns us to watch for false teachers who are wolves in sheep's clothing. Before long it is apparent that the person on the other end of the phone is not concerned about our prize . They are not representing our interests but theirs.
Some teachers do the same.
The most prominent name in their work is theirs. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. They will turn their ears away from the truth to turn aside to myths. However, these same people did not feel it was a violation of the Sabbath to circumcise a child on the Sabbath. They cold see that their act was consistent with what God desired but they couldn't see it with Jesus.
