It is clear that he does not pray, who, far from uplifting himself to God, requires that God shall lower Himself to him, and who resorts to prayer not to stir the man in us to will what God wills, but only to persuade God to will what the man in us wills.
Thomas AquinasFor those with faith, no evidence is necessary; for those without it, no evidence will suffice.
Thomas AquinasFor although the will cannot be inwardly moved by any creature, yet it can be moved inwardly by God.
Thomas Aquinas
