Galatians 6:7-10

7Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. 8For 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.

9And let us not be weary in well doing: for in due season we shall reap, if we faint not. 10As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith.
