Blaise Pascal was a 17th century Frenchman, who at age 31 experienced the presence of the God and wrote his memoriam that he then sewed inside his coat as a reminder. He was a mathematician and theologian (what a combination!), a real smart and heady guy; an academic, a thinker. Read what this man of the mind wrote:
In the year of grace 1654, Monday 23 November . . .
From about half-past ten in the evening till about half an hour after midnight.
God of Abraham. God of Isaac. God of Jacob.
Not of the philosophers and the learned.
Certainty. Joy. Certainty. Emotion. Sight. Joy.
Forgetfulness of the world and of all outside of God . . .
Joy! Joy! Joy! Tears of joy . . .
My God, will you leave me? Let me not ever be separated from you.
