The true lover of God keeps God ever in mind, and His love toward us and His benefactions. We see this even in human love, for we often remember the one we love. So whoever loves God remembers Him, thinks of Him, and finds consolation in Him, and is enrapt in Him. For wherever his treasure is, there his heart is also (Mt. 6:21). To him the priceless and most beloved treasury is God. Therefore his heart also holds itself inseparably before Him. Whence it is that he also remembers His holy name often and with love. For the heart filled with the love of God reveals outward signs of love. From this we see that those who forget God do not love Him, for forgetfulness is a manifest sign of no love for God. The lover can never forget his beloved.
Saint Tikhon of Zadonsk
