Teachers went to the churches of Galatia, persuading the Gentile converts to Christ that they must also be circumcised according to the Law of Moses, but Paul told the brethren that such persuasion did not come from the Lord, and Paul added that while circumcision may have seemed like a little thing, truly it was great, because if they kept one part of the Law, they would have to keep all the Law, and so he said,

A little leaven leavens the whole lump (Galatians 5.9).

He continued to express his confidence in them that they would do the right thing after hearing the instruction of his letter,

I have confidence in you, in the Lord, that you will have no other mind; but he who troubles you shall bear his judgment, whoever he is (Galatians 5.10).

Those who trouble the church, shall answer to the Lord for what they have done, but if we follow the Lord, we will have no other mind than to follow Him.
