'Requirements' in the Bible

who, [although they] know the requirements of God, that those who do such things are worthy of death, not only do they do the same [things], but also they approve of those who do [them].

They show that the essential requirements of the Law are written in their hearts; and their conscience [their sense of right and wrong, their moral choices] bearing witness and their thoughts alternately accusing or perhaps defending them

Therefore if an uncircumcised man keeps the law’s requirements, will his uncircumcision not be counted as circumcision?

in order that in our case the requirements of the Law might be fully met. For our lives are regulated not by our earthly, but by our spiritual natures.

Owe nothing to anyone except to love and seek the best for one another; for he who [unselfishly] loves his neighbor has fulfilled the [essence of the] law [relating to one’s fellowman].

Love does no wrong to a neighbor [it never hurts anyone]. Therefore [unselfish] love is the fulfillment of the Law.
