When you are in love, surely your constant concern is to be near the beloved at any and every opportunity, and you avoid anything that would hinder you from being in the company and society of your loved one. So it is when someone loves God. One constantly desires to be with him and speak with him. This can only be achieved through pure prayer, so let us apply ourselves to prayer with all our strength, for it makes us become like the Lord.
–Saint Theodorus the Ascetic (Seventh Century)
