20. The sins remaining in saints after conversion are various evil inclinations, lusts and desires natural to man and contrary to the Law of God. The saints, as well as others, are conscious of these sins, but with this difference: they do not permit themselves to be overcome thereby so as to obey the sins, allowing them free course; they do not yield to, but resist, such sins, and, as Paul expresses it here, incessantly purge themselves therefrom. The sins of the saints, according to him, are the very ones which they purge out. Those who obey their lusts, however, do not do this, but give rein to the flesh, and sin against the protest of their own consciences. They who resist their sinful lusts retain faith and a good conscience, a thing impossible with those who fail to resist sin and thus violate their conscience and overthrow their faith. If you persist in that which is evil regardless of the voice of conscience, you cannot say, nor believe, that you have God's favor. So then, the Christian necessarily must not yield to sinful lusts. 21. The Holy Spirit is given for the very purpose of opposing sin and preventing its reign. Paul says (Gal 5, 17): "For the flesh lusteth against the Spirit, and the Spirit against the flesh ... that ye may not do the things that ye would." And again (Rom 8, 13): "If by the Spirit ye put to death the deeds of the body, ye shall live." Also (Rom 6, 12): "Let not sin therefore reign in your mortal body, that ye should obey the lusts thereof." "For our passover also hath been sacrificed, even Christ." ["For even Christ our Passover is sacrificed for us."] 22. Here Paul assigns his reason for the statement just made--"Ye are unleavened." They are a new, unleavened or sweet lump, not because of any merit on their part, not because of their own holiness or worthiness, but because they have faith in Christ as the Passover sacrificed for them. This sacrifice makes them pure and holy before God. They are no more the old leaven they were when out of Christ. By this sacrifice they are reconciled with God and purified from sin. 23. Likewise for us God institutes a new ordinance, a new festival. The old has given place to something wholly new. A different and better Passover sacrifice succeeds that of the Jews. The Jews had annually to partake of their offered sacrifice, but they were not thereby made holy nor pure from sin. Theirs was a sign or earnest of the true Passover to come, the Passover promised by God, in the shed blood of which we are washed from sin and wholly healed--a Passover the partaking whereof we must enjoy by faith. We have now one perpetual and eternal Easter festival, wherein faith is nourished, satisfied and gladdened; in other words, we receive remission of sins and comfort and strength through this our Passover, Christ.
