10:27 Thou shalt love the Lord thy God - That is, thou shalt unite all the faculties of thy soul to render him the most intelligent and sincere, the most affectionate and resolute service.

If we desire to do this, perhaps the heart, which is a general expression, may be explained by the three following, With all thy soul, with the warmest affection, with all thy strength, the most vigorous efforts of thy will, and with all thy mind or understanding, in the most wise and reasonable manner thou canst; thy understanding guiding thy will and affections. De 6:5; Lev 19:18.

Sanctification
SANCTIFICATION [1] St Luke x. 42.--"One thing is needful." I have read many writings both of heathen philosophers and inspired prophets, ancient and modern, and have sought earnestly to discover what is the best and highest quality whereby man may approach most nearly to union with God, and whereby he may most resemble the ideal of himself which existed in God, before God created men.
