At this time in history, when the apostle John wrote these words, Christians had truly been influenced by false and heretical teachings. Some believed that Jesus did not exist in fleshly form. From this incorrect presupposition many people were led astray and even believed that they could not sin regardless of their lifestyle. Well, this false teaching had to be contended with.
Jesus is the saviour from our sins. Yet at the same time He is, also, our attorney before God. Those who do not deny Him, through their understandings and actions, will be blessed by His skills as a defense attorney. Those who follow false teachings about Jesus will not be able to have Him as their attorney. This would be unfortunate. Remember, we must have true and obedient faith in Jesus Christ.
