The fear of the Lord and the comfort of the Holy Spirit bring peace and growth to the church. Treating the Lord with contempt by religious fakery should remain a fearful prospect in the church. God is not mocked. And the Holy Spirit is a great comfort here, because it is precisely by his indwelling power that we become real and authentic.

Sin among the saints is more serious than sin among the lost. Sin against the Holy Spirit is very serious. 
Be on guard against hypocrisy in your life.
