Having taught us how to discern the spirits, John returns to the subject of love and adds further wonderful truths. We must love one another for by doing so, what is of the essence of God is communicated to us and becomes part of us.
Love cannot remain bottled up inside us but always finds some way to express itself. It is not love unless it is centred on another person. Love cannot simply be directed towards a scheme, and therefore we know that Christ loved us individually. We love the believer in recognition of his conversion, and we love the unbeliever in hope of his conversion.
John says that everyone who loves is born of God, but aren’t even unbelieving fathers capable of giving good gifts to their children? Are they also born of God? The love of those who have been born again is not the same as the love of the worldling. Only a believer can love God and all his attributes; only a believer can love Christians because they belong to Christ; only Christians can love the lost in the hope of seeing them saved. No one can love others who does not know the love of God towards his own soul, for his love will run out of resources.
