The constant contemplation of the glory of Christ will give rest, satisfaction, and complacency unto the souls of them who are exercised therein. Our minds are apt to be filled with a multitude of perplexed thoughts; – fears, cares, dangers, distresses, passions, and lusts, do make various impressions on the minds of men, filling them with disorder, darkness, and confusion.
But where the soul is fixed in its thoughts and contemplations on this glorious object, it will be brought into and kept in a holy, serene, spiritual frame. For “to be spiritually-minded is life and peace.” And this it does by taking off our hearts from all undue regard unto all things below, in comparison of the great worth, beauty, and glory of what we are conversant withal. See Phil. 3.7-11. A defect herein makes many of us strangers unto a heavenly life, and to live beneath the spiritual refreshments and satisfactions that the Gospel does tender unto us.
This is the sole foundation of all our meditations in this:
The glory that the Lord Jesus Christ is in the real actual possession of in heaven can be no otherwise seen or apprehended in this world, but in the light of faith fixing itself on divine revelation.
To behold this glory of Christ is not an act of fancy or imagination. It does not consist in framing to ourselves the shape of a glorious person in heaven. But the steady exercise of faith on the revelation and description made of this glory of Christ in the Scripture, is the ground, rule, and measure, of all divine meditations upon that.
