Theological argument: the existence of God. Understanding the need of the existence of God for the meaning of life and the rationality of faith

At first, it must be said that the existence of God is the great affirmation presupposed by the Bible. The Bible does not attempt to prove the existence of God, it simply takes this existence as a fact. The great Reformed theologian Louis Berkhof says: "For us the existence of God is the great presupposition of theology." In fact, no theologian could deny the existence of God, as this automatically would cause him to be without profession. But throughout history, philosophers and theologians have debated whether the human mind can be sure of God's existence. Does the existence of God is a matter that must be accepted by faith itself? Or is it possible, from reason and rational arguments to prove the existence of God?
