For an act to be good, it must arise from good motives. And one of those motives must be the glory of God. Where that motive is missing, every act has a fatal flaw. An unsaved man may have some good motives in what he does. That is, he may do something for the sake of others. That is fine, as far as it goes. We do not want to deny that. But it does not go far enough. God commands, “Whether you eat or drink or whatever you do, do it all for the glory of God” (1 Corinthians 10:31). But each thing the unbeliever does breaks this command. For that reason, he never once pleases God.
