First, we suffer for our own sake:
that we may learn who God is,                          Ps 46:1,10; Dn 4:24-37; the Book of Job,
that we may learn to trust                                 2 Cor 1:8-9
that we may learn to obey                                 Ps 119:67, 71,
discipline is proof of the Father's love
and of the validity of our sonship               ----Heb12:5-11,
it is the condition of discipleship                ----Acts 14:22; Lk 14:26-27, 33,
it is required of soldiers                                    2 Tm 2:4,

we are being "pruned" that we may bear fruit  Jn 15:2,
that we may he shaped to the image of Christ   Rom 8:29,
to qualify us to be fellow-heirs with Christ        Rom 8:17,
to qualify us for the kingdom of God                 2 Thess 1:4-5,
to qualify us to reign with Christ                        2 Tm 2:12,
that our faith may be strengthened                    Jas 1:3; 2 Thess 1:4-5; Acts 14:22,
that faith may be tested and refined                  Is 43:2, Dn 11:35; Mal 3:2; 1 Cor 3:13 Pt 1:7,
that we may reach spiritual maturity                  Jas 1:4,
power comes to its full strength in weakness    2 Cor 12:9,
to produce in us endurance, character, hope     Rom 5:3-4,
to produce in us joy and generosity                    2 Cor 8:2,

Second, we suffer for the sake of God's people:
 that they may obtain salvation                          2 Tm 2:10,
 to give them courage                                         Phil 1:14,
 that because of death working in us,                2 Cor 4:12, Gal 4:13;
  life may work in them                                       1 Jn 3:16,
 that grace may extend to more                         2 Cor 4:15,
 that our generosity may bless others               2 Cor 8:2

Third, we suffer for the world's sake:
 that it may be shown what love and                  The Book of Job; Jo 14:31;
  obedience mean                                                Mt 27:40-43,
 that the life of Jesus may be visible in
  ordinary human flesh                                        2 Cor 4:10
 

Fourth, we suffer for Christ's sake:
that we may be identified with                            Gal 2:20,
  Him in His crucifixion
suffering is the corollary of faith                        Ps 44:22; Acts 9:16 and 14:22;2
                                                                             Tm 3:12; Jn 15:18-21; 1Thess 1:6 and 3:4,
  that we may share His suffering                      1 Pt 4:12-13; Phil 1:29, 2:17 and 3:8, 10
                                                                             Col 1:24; 2 Tm 1:8; Heb 13:13,
  that we may share His glory.                            Rom 8:17-18; Heb 2:9-10, 2 Cor 4:17.
