In "Doctrinal Discussion" Don Englund writes:
Evangelist “Big Ray” Smith used to point out that repentance involves three actions — one that is almost wholly the responsibility of the Holy Spirit, another that is partly the responsibility of the seeker and partly the responsibility of the Holy Spirit, and a third that is almost wholly dependent upon the individual. First, it is within the office of the Holy Spirit to make the sinner aware of sin, and that an undebatable consent to and a yielding to evil has occurred. Second, repentance involves a change in attitude toward sin which is partly the work of the pleading sinner and partly the work of the Holy Spirit. Finally, the element of repentance that is dependent upon the individual is that of turning from sin. Big sins, little sins, and all others must come to an abrupt halt in the new Christian's life, rather than just tapering down slowly.
