The apostle Paul warns of the serious danger that attends an attempt to mock God, that is, the danger that comes to one who thinks that the principles of God’s administration can be treated with contempt or can successfully be evaded. He writes to the Galatian Christians: “For if anyone thinks he is something when he is nothing, he is deceiving his own mind. . . . Do not be misled: God is not one to be mocked. For whatever a man is sowing, this he will also reap; because he who is sowing with a view to his flesh will reap corruption from his flesh, but he who is sowing with a view to the spirit will reap everlasting life from the spirit.”—Ga 6:3-8.
Here the apostle shows that a person should not deceive himself with a false estimate of his own worth, thereby ignoring God and his Word. He should clean up his life to walk by the spirit as the Word directs. If a person does not do this, but instead goes on sowing with a view to fleshly desires, he is ‘accepting the undeserved kindness of God and missing its purpose’ and is treating God’s instruction as contemptible. (2Co 6:1) He may deceive himself into thinking that he is safe. Nevertheless, God knows his heart and will judge him accordingly.
