The flesh is unholy. All that you do in the flesh is not Godly, but that is why we are not gods. We are the flesh, and God's spirit is within us. It is the source of life for our flesh, and we grow that spirit with love and happiness that we have in our flesh. Have love and happiness in the flesh and grow your spirit for God who is love and happiness. Christians do not teach this because they worship the flesh as a god, and they will burn in hell for denying the spirit.
