Defend the truth; make sure that these things are taught. Make sure that the dear people of God are warned not to listen to false teachers.
There is a tendency today to say the opposite, to be all embracing, to be warm to all naming the name of Christ: ‘Let us try to reach some form of unity.’ This is a sensitive subject. We do not want to cut ourselves off from all who are even a little different from us., and to have a negative spirit. But John says, watch out; examine all things carefully. Maybe there is a fine church, but what would happen if false teachers got in? Many wil make shipwreck of their faith, or the testimony to the town will be ruined. Maybe the Sunday School has built up good will in the neighbourhood but there could be a setback. Let us be careful not to lose what we have worked for.
