God's chief glory is His love. It's what makes Him God, and a God worth loving in return, Man's very purpose, his telos, is to come to know and love God with his whole heart, soul, mind, and strength, by knowing His love, and by that coming to love our neighbor as He does as well. That relationship, that love, itself, is the basis of unending, uncompromised sheer bliss, happiness, and ecstasy for man-that's what Love desires for the other: the best. God wouldn't have it any other way. We're to respond as He draws us into His love, to come to value and appreciate it as the highest Good-because He is that love.
