Jamieson, Fausset and Brown on 2 Timothy 2:10

10. Therefore--Because of the anxiety I feel that the Gospel should be extended; that anxiety being implied in 2Ti 2:9.

endure--not merely "I passively suffer," but "I actively and perseveringly endure," and "am ready to endure patiently all things."

the elect's sakes--for the sake of the Church: all the members of Christ's spiritual body (Col 1:24).

they ... also--as well as myself: both God's elect not yet converted and those already so.

salvation ... glory--not only salvation from wrath, but glory in reigning with Him eternally (2Ti 2:12). Glory is the full expansion of salvation (Ac 2:47; Ro 8:21-24, 30; He 9:28). So grace and glory (Psa 84:12).
