No man can rightly define God's glory any more than a man can define him. Glory is the fullness of God, and that is a subject too high for our finite minds. However, we do know in part.
When God gives his glory, he gives himself. The one who receives his love also gets his mercy, holiness and strength. The one who receives his mercy also gets his love and all else that is the fullness of God. Those who seek the glory of God must learn that he truly desires to give himself to us, which means he wants us to enjoy the fullness of rest and confidence.
Before he left the earth to return to his heavenly Father, Jesus prayed, “And now, O Father, glorify me together with yourself, with the glory which I had with you before the world was. I have manifested your name to the men whom you have given me out of the world. They were yours, you gave them to me, and they have kept your word” (John 17:5-6, NKJV).
Jesus was in the bosom of the Father before the world was. He was one with the Father, and that was glory. Union with the Father was the delight and glory of his being. He had intimacy, union and oneness.
We know so little of his glory. We think only in terms of cosmic power and splendor. We are such strangers to the real meaning of God's glory that we don't even understand what Jesus meant when he said, “All mine are yours, and yours are mine, and I am glorified in them” (John 17:10).
Did you not know that Jesus Christ is glorified in his saints now? He abides in us in all his divine fullness. We are complete in him. When he comes to abide, he comes in all his glory, might, majesty, holiness, grace and love. We have received the glory of a full and complete Christ. We have an open heaven. Let us come boldly to the throne of his glory and make our petitions known. How wonderful it is to come away with assurance and hope!
