Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. – Galatians 6:7
Mockery is a horrible thing. More cowardly than a punch and more humiliating than a rebuke, mockery is only good for tearing down without the means to rebuild. While there is a place in the life of a Christian to criticize, there is no place for mockery or scorn.
“Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful” (Psalm 1:1). The very purpose of the Church is to build and not destroy except to rebuild. This is why God inspired apostles, prophets, preachers, and teachers “…for the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:  Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ…” (Ephesians 4:11-13).
Whether the mockery is verbal or through flagrant disobedience to God’s Word, He is not mocked. Like gravity, God’s promises as definitive. Whether for blessing or cursing, God’s will cannot be refuted. He will not be mocked. We will reap what we sow.
For this reason, the Apostle Paul stressed holiness along side his emphasis on the sovereign grace of God, saying, “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. And let us not be weary in well doing: for in due season we shall reap, if we faint not. As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith” (Galatians 6:8-10).
