7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
8 For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
An outward show of Christianity without a change of heart mocks God and grieves the Holy Spirit. Pretending to believe leads to a hardened heart and a seared conscience. Instead, let us be strong in our faith and reap eternal life.
