Calvin
- 2:1
- John - along with the gospel in general - declares that we must depart from sin, yet recognizes that we will always sin and need forgiveness again. This is not license to sin freely, but a recognition of our fallen nature. To the degree that flesh is able, we should abstain from sins, but 'though heaven should fall and all things be confounded, yet this part of truth ought never to be omitted': that Jesus died that our sins might be forgiven. We should preach of the grace that pardons us, even though some will abuse that grace as license, and others will take offense at the abuse - blaming it on the message. Though we admittedly will sin daily, the cure is provided in our advocate - Christ Jesus. He alone is the source of our righteousness and salvation. 'If' is not taken to indicate that some might manage to never sin, but to point out the cure required when we sin. Christ appears before God, that we may be reconciled. "…The sins by which they are entangled, do not prevent them from becoming just…" Two titles are given Christ here: just (righteous) and propitiation. Righteousness is required of one who would reconcile us with a righteous God. (Heb 7:26 - our high priest needs to be holy and undefiled.) Propitiation, or sacrifice, was ever a requirement for God's priests. The two combine to show that only Jesus could fill the role of advocate. Christ's role should not be transferred to anybody else, as the RC has done with dead saints. The dead have not the credentials for advocacy. This does not rule out our praying for one another, for in so praying we still call out to Jesus alone. Jesus doesn't plead with the Father on His knees, for he pleads for us with His equal, and His sacrifice remains sufficient.
- 2:2
- Christ's work extends "to all who by faith embrace the gospel". 'All' doesn't include the reprobate under its banner, nor Satan as the chief reprobate. It does include all the elect, all who have believed the gospel message, and accepted God's grace.
- 2:3
- Having reminded us of God's work on our behalf, John now moves to God's requirements for us: namely obedience and love to God. By this it is made clear that mere profession of belief means nothing without a matching life. To know God must necessarily change us - change our feelings. Knowledge of God leads both to [reverent] fear and love. The gospel is "a lively mirror in which we contemplate the image of God, and are transformed into the same." (2Co 3:18 - dimly seeing God's glory, we are transformed from glory to glory.) We cannot know that we know Him until we first know Him. John doesn't mean to imply that we can come to perfect conformance with God's commandments, but that we strive to our utmost to do so. When Scripture speaks of our righteousness, it doesn't exclude remission of sins, it starts there. This doesn't imply that faith depends on works, only that works are added as evidence of faith. Certainty of faith depends on Christ's grace alone, but works serve to distinguish true faith from mere knowledge. (Col 3:9 - we have set aside our old life.)
- 2:4
- John knows that many profess Christianity without true faith, else he wouldn't waste time writing this part. Since truly knowing God must lead to change, lack of change belies true knowledge.
- 2:5
- The core of obedience to God's law is to love God. (Dt 10:12 - love and obedience to God are His requirements, Dt 30:19-20 - life is chosen by love and obedience to God.) The perfect love of God is the complete keeping of His law - which includes our duty of brotherly love. This isn't going to happen in this life, but - as in knowledge - we ought to be making progress in this keeping of the law. Since love is shown in obedience, and fellowship isn't possible without love, our obedience serves to give us confidence of our fellowship and our faith.
- 2:6
- John doesn't merely call us to imitate Christ, but shows that our union of fellowship ought to lead inexorably to our being like Him.
