God created us only so that we could share in His joy. It is were not true God created us so that we could share eternally in His Life, existence would have absolutely no meaning; the world would be absurd. It is only in faith in the intentions of God’s love that the world finds its meaning. There world has no other justification than its having been destined in Christ for divine beatitude. This is the response to all those who would object that “a good God would not have been able to created a world so full of misery and suffering.” St Paul responds that it is through this that God seeks to build — and will irrevocably and ultimately succeed in building — the city of God in which his children will be bathed in the light of the Trinity.
