A friend on theooze.com posted a link to this essay. It’s an excellent piece on “proving” the existence of God. I would suggest you read the entire essay.
A few paragraphs struck me as significant:
“The existence of God is a profound matter, and never something that should be treated perfunctorily. That “I believe God exists” and that “I know Him” are among the deepest things that a Christian can say, and are a confession of the grace of God. We have been given something that is consonant with purity of heart, and should thus confess it with extreme humility.”
“We are living in a time of history in which saints are required. We have long passed the time in which rational arguments will carry the day. Nothing less than lives which manifest the existence of God will do. The world has heard centuries of arguments – has been subjected to crass persecutions and atrocities in the name of God (even if these were largely not the result of Orthodox actions). We have survived a century of extremes (Bolshevism, Nazism, etc.). That the world is hungry is beyond doubt. But the world is not hungry for a new and winning argument.
The world hungers for God (whether it knows this or not).”
“The proper Christian answer to the hunger of the world is to be found only in the manifestation of God. Thus the challenge of a modern atheist should not be met with an anxious rejoinder from our panoply of arguments – but with the urgency of prayer that we might ourselves become an answer through the reality of the presence of God in our lives.”
“As witnesses of the God who exists – we should strive in our small ways – to become persons whose lives are themselves an argument for the existence of God – a God whose existence is indeed beyond all existence.”
“It is a tall order. Nothing less than life in the image of the resurrection of Christ will do. Nothing less than that has been promised us in Christ.”
May we be people who live in the reality and power of the resurrection.
