Peterson states that it's responsibility—not happiness—that provides the meaning that sustains one through the vicissitudes of life. And while I agree with this, I think that such a view has a missing element…which is to say…hope. For when one has hope, one has yet another source or resource that can often enable one to endure even the worse of circumstances.
For example, the Message Bible states that God will never let you down—never walk off and leave you. Or as the Amplified Bible puts it, God will never, under any circumstances, desert you, nor give you up or leave you without support, nor will He in any degree leave you helpless, assuredly not!
The thought from Psalm 23:4, again in the Message Bible, is that even when I find myself in the valley of death, I'm not afraid because God is with me, walking by my side—the One who, by means of his Spirit working deeply and gently within me, can do far more than I could even imagine or guess or request in my wildest dreams, as paraphrased from the Message Bible.
So, if one lives life not only with responsibility, with the knowledge that s/he is God's workmanship, created in the Son for the good works that God prepared before the foundation of the earth for that individual to fulfill; but also lives life in hope, knowing that God has plans for us,
"plans to prosper you and not to harm you, plans to give you hope and a future," then one has TWO powerful meaning-making insights to bolster and strengthen his or her spirits in those times when it is needed the most.
