I know quite well that not everyone of the godly is privileged, with the three disciples, to behold Jesus in His glory on the mount, or with Paul, to be drawn into the third heaven. I also know that some who read this will become distressed, and sink down in discouragement, thinking, “How dark it is within me, how inferior is my spiritual life; never during my lifetime shall I attain to such a view of Jesus in His glory!” Know, however, that to be acquainted with these matters mentioned, to perceive a stirring of love, a desire, and a yearning for these things within as you hear or read concerning them, and to be distressed and sorrowful because you are so far from all this, are evidences of the principles of grace. Therefore such motions ought to stir us up to actively strive for this. If we persevere in prayer, waiting, hoping, and believing, we shall discover that the Lord will reveal Himself to such. Therefore, “Be of good courage, and He shall strengthen your heart” (Ps 31:24)
