1 John 3:1-10
Intro:
John was aware that Christians sin (2:1). They can receive forgiveness through Jesus’s death (1:7) as they confess their sins (1:9). By everyone who sins has not seen him or known him, John had in mind flagrant sin by false “believers” whose confession of Jesus was false (2:23), whose love was set on the world rather than God (2:15), and whose obedience was lacking (2:4). Jesus himself warned about people who called him “Lord” and did great things in his name, but ultimately were not genuine disciples (Mt 7:21–23).
If, then, the whole purpose of Christ’s first appearing was to remove sins and to undo the works of the devil, Christians must not compromise with either sin or the devil, or they will find themselves fighting against Christ. If the first step to holiness is to recognize the sinfulness of sin, both in its essence as lawlessness and in its diabolical origin, the second step is to see its absolute incompatibility with Christ in his sinless person and saving work. The more clearly we grasp these facts, the more incongruous will sin appear and the more determined we shall be to be rid of it.
