John Wesley on Luke 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. We may safely rest in this general sense of these important words, if we are not able to fix the particular meaning of every single word. 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.
