Human progress is neither automatic nor inevitable. Every step toward the goal of justice requires sacrifice, suffering, and struggle; the tireless exertions and passionate concern of dedicated individuals.
God has reserved to Himself the right to determine the end of life, because He alone knows the goal to which it is His will to lead it. It is for Him alone to justify a life or to cast it away.
When ours are interrupted, his are not. His plans are proceeding exactly as scheduled, moving us always (including those minutes or hours or years which seem most useless or wasted or unendurable) "toward the goal of true maturity" (Rom 12:2 JBP).
