The kingdom of Christ is already in this world, though not of it. That kingdom is two-fold, perfect in heaven, imperfect on earth. We pray that God’s kingdom of grace may be extended in the souls of men, and that they may so fulfill the will of God that they may attain that final happiness of the kingdom of heaven. But the words you quote in no way refer to another temporary state, or to any second chance.
