ANSWER: The word flesh has both a good and a bad meaning. In this text flesh means the domination of evil inclinations. No man who is thus dominated can please God. But when the evil propensities are controlled by the regenerating Holy Spirit, God is pleased. Every man in the world may please God by repentance and faith in Jesus Christ. The flesh may not only be controlled but be crucified.
