to the end that you should walk worthily of God, who calls you into his own Kingdom and glory.
Calleth you into his own kingdom and glory ...  The kingdom of God presently exists in the community of Christians on earth, that kingdom having been set up on the first Pentecost following the resurrection of the Son of God from the dead; but there will be an eternal phase of the kingdom, mentioned by Peter  (2 Peter 1:11).  By using one possessive for "kingdom" and "glory" Paul indicated that just one kingdom is in view; but, since the present phase of God's kingdom is not one of glory (in the ultimate sense), it is probable that Paul indicated (by the word "glory") the same eternal phase mentioned by Peter.
