Mutual communion is the soul of all true friendship; and a familiar converse with a friend hath the greatest sweetness in it…[so] besides the common tribute of daily worship you owe to [God], take occasion to come into His presence on purpose to have communion with Him. This is truly friendly, for friendship is most maintained and kept up by visits; and these, the more free and less occasioned by urgent business, or solemnity…. The more friendly they are… We used to check our friends with this upbraiding. “You still [always] come when you have some business, but when will you come to see me?' ...When you come into His presence, be telling Him still how well you love Him; labor to abound in expressions of that kind, than which…there is nothing more taking with the heart of any friend.
