WATCH – Dear one, realize for yourself and all each day, clear and strong, that the Christ, Truth, does not merely open “the windows of heaven” for us, or promise us heaven, but the knowledge of the Christ in Christian Science is heaven here and now.  This knowledge of Truth as it is taught in Science is heaven’s open door for all.  Mary Baker Eddy
(Carpenter, Gilbert, Watches, Prayers and Arguments, p.6)
