John 17:22 - Matthew Poole's English Annotations on the Holy Bible

By glory here some understand the heavenly glory; but then they must understand the oneness mentioned in the latter part of the verse, of the union which the saints shall have with Christ and his Father in glory, in another world. Others understand the Divine nature, of which the apostle in, 2 Peter 1:4, saith, believers are made partakers: this seemeth to come nearer, for the more men and women are made partakers of that, the more they will study the unity of the Spirit. Others understand the power of working miracles, by which Christ is said to have manifested his glory, 1 Thessalonians 2:11; and the effect of this power is called the glory of God, 1 Thessalonians 11:40. Others understand the preaching of the gospel, in which the ministration of the Spirit is glorious, 2 Corinthians 3:8; and the faithful ministers of the gospel are called the glory of Christ, 2 Corinthians 8:23. That they may be one, even as we are one; our Saviour either again repeats his prayer, that they might be one; or else declareth that he had communicated his power, his glory to them, that they might be one, as be and his Father are one.
