That which is altogether just shalt thou follow, that thou mayest live.
Deut. xvi. 20.

This day the Lord thy God hath commanded thee to do these statutes and judgments: thou shalt therefore keep and do them with all thine hearty and with all thy soul.
Deut. xxvi. 16.

NEVER pass by or palter with the clear voice of conscience, with the plain command of duty; never let it be doubtful to your own soul whether you belong to the right side or wrong, whether you are a true soldier or a false traitor. Never deliberate about what is clearly wrong, and try to persuade yourself that it is not.
Frederick Temple.

The first resolve of one who gives himself wholly to God must be never to give way deliberately to any fault whatever; never to act in defiance of conscience, never to refuse anything God requires, never to say of anything, It is too small for God to heed. Such a resolution as this is an essential foundation in the spiritual life. I do not mean but that in spite of it we shall fall into inadvertencies, infirmities, errors; but we shall rise up and go on anew from such faults — because they are involuntary, the will has not consented to them.
Jean Nicolas Grou
