Do not be deceived; God is not mocked, for whatever a man sows, that he will also reap. For he who sows to his own flesh will from the flesh reap corruption; but he who sows to the Spirit will from the Spirit reap eternal life. And let us not grow weary in well-doing, for in due season we shall reap, if we do not lose heart. So then, as we have opportunity, let us do good to all men, and especially to those who are of the household of faith.
–Galatians 6:7-10
