The flesh takes what is good in life, warps it, and makes it evil. For example, man was created with a desire to worship God, but because of Adam s sin, mankind has the pull to idolatry. History is but a catalogue of the working of man s flesh. This body is the arena for sin. Sin controls the members of one s body, the deeds of the body.
Sin is described as sin in one s members.
Now to balance this thought, the Bible also teaches that one is hostile against God in regard to the mind. Many of the works of the flesh, begin with the mind. Temptation begins in the mind. Some temptations are triggered because of the body itself such as the first four works of the flesh. So our twisted capacities within often use the body to sin.
