Whom have I in heaven but thee? and there is none upon earth that I desire beside thee? (Psalm 73:25)
 
For who in the heaven can be compared unto the LORD? who among the sons of the mighty can be likened unto the LORD? (Psalm 89:6)

The saints of old desired the light of the knowledge of the glory of God in the face of Jesus Christ. There was an abiding hunger for the person of the LORD. The Old Testament saints weighed the Lord in the balances against all persons -in heaven above and earth beneath- all came up wanting. This love and hunger for the Lord passed the desire of men for spousal embrace. The Lord Jesus Christ became their all in all.

Can we do anything less in the New Testament economy? We, who have the highest revelation in the face of His dear Son, should ache, hunger, and thirst for Him at all times; so that, we can with joy agree with the Apostle Paul. But what things were gain to me, those I counted loss for Christ. Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ. (Philippians 3:7-8)

This, therefore, is the highest, the best, the most useful object of our thoughts and affections. He who hath a real view of this glory, though he know himself to be a poor, sinful, dying worm of the earth, yet would he not be an angel in heaven, if thereby he should lose sight of it; for this is the centre wherein all the lines of the manifestation of the divine glory do meet and rest. … Look unto the things of this world, -wives, children, possessions, estates, power, friends, and honour; how amiable are they! How desirable unto the thoughts of most of men! But he who hath obtained a view of the glory of Christ, will, in the midst of them all, say, … one glance of thy glorious beauty upon me hath quite overcome me, -hath left no heart in me unto things here below! If it be not thus with us frequently, -if we value not this object of our minds and affections, -if we are not diligent in looking up unto him to behold his glory, -it is because we are carnal, and not in any good measure partakers of the promise, that “our eyes shall see the King in his beauty.” (John Owen, The Glory of Christ, 314)
