"For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed" (Romans 8:18)
God's loving motive [in discipline] is to bring us into total harmony with Himself so that moral power and holy usefulness become ours in this world and in the world to come.

In summary: Down here the orchestra merely rehearses; over there we will give the concert. Here, we ready our garments of righteousness; over there we will wear them at the wedding of the Lamb.
God's richest blessings often require not only sacrifice, suffering and conflict, but long delay and patient waiting. But the blessing grows with the delay. The interest gathers with the extended time, and God's ratio is always compound interest.
