Sins are offenses against the law of love, the law of Christ, which is thus epitomized by John, "And this is His commandment, that we should believe on the name of His Son Jesus Christ, and love one another" (I John iii. 23). Hence the Spirit convinces the world of sin, "because they believe not on Me." The sum total of God's commandments to men with the New Testament in their hands, is faith in Christ, attested by its proper fruits, good works. However dwarfed and shattered by sin that poor drunkard is, so long as he is this side of the gates of hell he is under the dispensation of the Holy Spirit, who imparts to him the gracious ability to repent of sin, and to trust, love, and obey the Lord Jesus. His refusal is sin. So long as he has any capacity for love, however small, that capacity is called his whole heart. The law of love says to him in tones of authority, "Thou shalt love the Lord thy God with all thy heart." Hence every one is under obligation to be evangelically perfect. Refusal to love with the whole heart is the ground of condemnation, and not inevitable failures in keeping the law of Adamic perfection.
