All of us today are well aware that by the term "Heaven" we are not referring to somewhere in the universe, to a star or such like; no. We mean something far greater and far more difficult to define with our limited human conceptions. With this term "Heaven" we wish to say that God, the God who made himself close to us, does not abandon us in or after death but keeps a place for us and gives us eternity. We mean that in God there is room for us. To understand this reality a little better let us look at our own lives. We all experience that when people die they continue to exist, in a certain way, in the memory and heart of those who knew and loved them. We might say that a part of the person lives on in them but it resembles a "shadow" because this survival in the heart of their loved ones is destined to end. God, on the contrary, never passes away and we all exist by virtue of his love. We exist because he loves us, because he conceived of us and called us to life. We exist in God's thoughts and in God's love. We exist in the whole of our reality, not only in our "shadow". Our serenity, our hope and our peace are based precisely on this: in God, in his thoughts and in his love, it is not merely a "shadow" of ourselves that survives but rather we are preserved and ushered into eternity with the whole of our being in him, in his creator love. It is his Love that triumphs over death and gives us eternity and it is this love that we call "Heaven": God is so great that he also makes room for us. And Jesus the man, who at the same time is God, is the guarantee for us that the being-man and the being-God can exist and live, the one within the other, for eternity. 

This means that not only a part of each one of us will continue to exist, as it were pulled to safety, while other parts fall into ruin; on the contrary it means that God knows and loves the whole of the human being, what we are. And God welcomes into his eternity what is developing and becoming now, in our life made up of suffering and love, of hope, joy and sorrow. The whole of man, the whole of his life, is taken by God and, purified in him, receives eternity. Dear Friends! I think this is a truth that should fill us with deep joy. Christianity does not proclaim merely some salvation of the soul in a vague afterlife in which all that is precious and dear to us in this world would be eliminated, but promises eternal life, "the life of the world to come". Nothing that is precious and dear to us will fall into ruin; rather, it will find fullness in God. Every hair of our head is counted, Jesus said one day (cf. Mt 10: 30). The definitive world will also be the fulfilment of this earth, as St Paul says: "Creation itself will be set free from its bondage to decay and obtain the glorious liberty of the children of God" (Rom 8: 21). Then we understand that Christianity imparts a strong hope in a bright future and paves the way to the realization of this future. We are called, precisely as Christians, to build this new world, to work so that, one day, it may become the "world of God", a world that will surpass all that we ourselves have been able to build. In Mary taken up into Heaven, who fully shares in the Resurrection of the Son, we contemplate the fulfilment of the human creature in accordance with "God's world". 

Let us pray the Lord that he will enable us to understand how precious in his eyes is the whole of our life; may he strengthen our faith in eternal life; make us people of hope who work to build a world open to God, people full of joy who can glimpse the beauty of the future world amidst the worries of daily life and in this certainty live, believe and hope. Amen!
