John writes again to the same congregation for which he has much love and tender affection for. He writes to warn them about specific deceivers that have gone out and are seeking to infiltrate the church. The church must be on guard against any person or doctrine claiming to go ahead, progress or advance the original message of the gospel delivered once for all to the saints. For such persons who would disseminate such a message, indeed a false gospel, we, individually and corporately, must have nothing to do with them.
John has written that the church might be assured of their salvation and confirmed in their understanding of the gospel. He now concludes that though the world is in the control of the evil one, the church- which finds its origin, being and life in Christ- is secure as it is protected by Christ.
When we have assurance of our salvation, knowing that we are His children, we can have confidence in prayer. We can rejoice that all of our requests that are according to his will shall be answered! God will even use our prayers for a wayward or backslidden brother or sister as the means of reviving them again and restoring them in faith.
Our text this week paints a picture of what Christian community ought to look like and how we can achieve it. Colossians 3:12-17 points to our motivation and model for right conduct within the family of God and also shows us the only means by which we can hope to grow into the kind of community God desires.
