'Faculties' in the Bible

and no longer lend your faculties as unrighteous weapons for Sin to use. On the contrary surrender your very selves to God as living men who have risen from the dead, and surrender your several faculties to God, to be used as weapons to maintain the right.

your human infirmity leads me to employ these familiar figures--and just as you once surrendered your faculties into bondage to Impurity and ever-increasing disregard of Law, so you must now surrender them into bondage to Righteousness ever advancing towards perfect holiness.

For whilst we were under the thraldom of our earthly natures, sinful passions-- made sinful by the Law--were always being aroused to action in our bodily faculties that they might yield fruit to death.

I plead with you therefore, brethren, by the compassionsof God, to present all your faculties to Him as a living and holy sacrifice acceptable to Him. This with you will be an act of reasonable worship.

Such persons are mere babes. But solid food is for adults--that is, for those who through constant practice have their spiritual faculties carefully trained to distinguish good from evil.
