While the will is the ultimate determiner of all choices, it is influenced in its choices by the strongest forces brought to bear upon it. These compelling forces come from a variety of sources. It may be the subtle suggestions of Satan and his world system (Eph. 2:2) or the evil enticements of our own sinful nature (Jas. 1:14). It may be the urgent voice of conscience, the earnest reasoning of a loving friend, or the quiet prompting of the Holy Spirit. But from whatever source these compelling forces come, they reach our wills through either our reason or our emotions.
