From a Commentary on Ps. 99

“If you want some idea who He is, you must draw nearer to Him. To look from a distance is to risk being deceived. It is the spirit that perceives Him and the heart that sees Him. What sort of heart? “Blessed are the pure in heart: they shall see God” (Mt. 5:8).

You must draw nearer to Him by becoming like Him. You will feel His presence to the extent that love grows in you, because God is Love.

Then you will not be able to do anything but praise Him. And if you make a joyful noise to the Lord, you will understand the joyful noise that all the lands make to Him.”

~St. Augustine
