Λευιτικόν 8:21

Verse 21. Moreover, all sensual and natural affections must be purified by the application of the truths of the Word; and thus the internal man must be wholly consecrated to the Lord; for by such consecration, heavenly peace and rest are realized; it is indeed the worship of the Lord from pure love, by influx from Him and by co-operation with Him through obedience to the truths of the Word.
