John is so delighted when he thinks about the type of love that God gives to His children. Someone has described it as exotic love that is completely foreign to the human heart.
Despite the fact that those of us who are saved are children of God we are not yet 'the finished article' as far as God is concerned. We will always fall short of being what God wants us to be. This will be true until we get to heaven. In that day we will fully understand what the Lord Jesus is like because by then we shall be like him. That's another amazing truth!
The section ends by encouraging Christians who eagerly await the coming of the Lord Jesus to keep themselves pure just as the Lord Jesus is pure. This will mean that we must live our lives in way that pleases God. To do this we need to be careful about what we get involved in, what we read, watch and think about. The glorious fact is that our Saviour is pure and we are going to be like Him one day.
