And the glory which You gave Me I have given them, that they may be one just as We are one:
When God made man, the Bible says that God crowned him with glory and honour. The word crowned here means to encompass or to surround like a glorious circle. The glory of God was therefore man’s clothing. In other words, Adam’s whole being was gloriously radiant.
When man sinned against God, he forfeited the glory of God. But when Jesus Christ was born, the glory of God came down. And many years later, Jesus, before He died, said to His Father, “The glory which You gave Me I have given them, that they may be one just as We are one.”
So the glory of God which man forfeited has now been restored to him because Jesus has come. When He died on the cross, He took our shame, gave us His righteousness and restored the glory of God to us.
But what exactly is the glory of God? ‘Doxa’, the Greek word for “glory” here, means having a good opinion concerning one that results in praise, honour and glory. This means that in restoring to us His glory, God wants us to have the sense that we are praiseworthy, honourable and glorious because of His constant good opinion of us!
 Ps 8:4,5 What is man that You are mindful of him, And the son of man that You visit him? 5 For You have made him a little lower than the angels, And You have crowned him with glory and honor.
 Ro 3:23 for all have sinned and fall short of the glory of God.
 Lu 2:9 And behold, an angel of the Lord stood before them, and the glory of the Lord shone around them, and they were greatly afraid.
