Beloved, I beg you as foreigners and pilgrims, to abstain from fleshly lusts, which war against the soul;
By the lusts or desires of the flesh he means not only those gross concupiscences which we have in common with animals, as the Sophists hold, but also all those sinful passions and affections of the soul, to which we are by nature guided and led. For it is certain that every thought of the flesh, that is, of unrenewed nature, is enmity against God. (Romans 8:7.)
