Doesn't it move you to find the apostle John in his old age devoting the best part of one of his epistles to exhorting us to follow this divine teaching? The love that ought to exist amongst us Christians is born of God who is Love. 'Beloved let us love one another; for charity comes from God, and he who loves is born of God and knows God. He who has no love does not know God, for God is Love.' He focuses on fraternal charity because through Christ we have become children of God: 'See what love the Father has shown towards us, that we should be called children of God, and should be such.'

At the same time as he raps sharply on our consciences to make them sensitive to God's grace, he also insists that we have received a marvellous proof of the Father's love for men, 'By this was made manifest the charity of God for us, that God sent his only begotten Son into the world, so that we might live through him.' It was the Lord who took the initiative by coming out to meet us. He gave us this example so that we might join him in serving others, generously placing our hearts on the ground, as I am fond of saying, so that others may tread softly and find their struggle more pleasant. This is how we should behave because we have been made children of the same Father, that Father who did not hesitate to give us his dearly beloved Son.
