O thou who dost believe in the Spirit of Christ, in the Kingdom of God!
The body is composed, in truth, of corporeal elements and every composition is necessarily subject to decomposition; but the spirit is an essence, simple, pure, spiritual, eternal, perpetual and divine. He who seeketh Christ from the point of view of His body hath, in truth, debased Him and hath gone astray from Him; but he who seeketh Christ from the point of view of His Spirit will grow from day to day in joy, attraction, zeal, proximity, perception and vision.
Thou hast then to seek the Spirit of Christ in this marvelous day. The heaven whither Christ ascended is not an infinite space. His heaven is much rather the kingdom of His Lord, the Munificent. As He said, “The Son of Man is in heaven.” It is known then that His heaven is beyond the boundaries that surround existence and that He is elevated for the people who adore.
Pray God to ascend to this heaven, to taste of its food—and know thou that the people have not understood to this day the mystery of the Holy Scriptures. They believe that Christ was deprived of His heaven when He was in this world, that He had fallen from the heights of His elevation and that later He ascended to this elevated pinnacle—that is to say, towards the heaven which doth not exist, for there is only space. They expect that He will descend from this heaven seated upon a cloud. They believe that there is in the heavens a cloud upon which He will be seated and by which He will descend; while, in reality, the clouds are vapors which rise from the earth and which do not descend from the heavens. The cloud mentioned in the Holy Scriptures is the human body, because it is a veil for them, like a cloud, which prevents them from seeing the Sun of Truth which is shining in the horizon of Christ.
I pray God to open before your face the gates of revelation and of vision in such a way that thou shalt learn the mysteries of God in this known day.
