I believe the fact that we are born with a sense of how things ought to be is evidence that God exists and that we’re living in a fallen world.

My friend Stacey’s daughter Alisha (like Brett) was born with severe disabilities. Sometimes Alisha giggles for no apparent reason. Often this involuntary giggling occurs at inappropriate times, times when they wish she would remain quiet, like during their meal time prayers.

Stacey tells of a time when her son Caleb was only five years old and became a tad irritated with her giggling during their prayers. When the prayer ended, he asked, "Why did you get her anyway?" (implying she hadn't been one of their better decisions) 

When they told him they’d gotten her before him, he asked exasperatedly, “Well then why doesn’t God just heal her up?" 

Caleb had never known a life without Alisha. It was only as he got a little older that he began to realize how much easier their life would be if God would just "heal her up.” 

I don’t know why God allowed Alisha and Brett to be born with severe disabilities or why He doesn't just “heal them up.” I can only share that I choose to trust in God's Word and His promises, to acknowledge that as far as the heavens are higher than the earth, so are His ways higher than my ways and His thoughts higher than my thoughts. (Isaiah 55:9) 

Of course there have been blessings unveiled in some of the difficulties, but the sharp ache of Brett not being what I think he ought to be never goes away entirely and sometimes it's overwhelming in its intensity. 

The apostle Paul's claim that he was "perplexed but not in despair" (2 Cor. 4) epitomize how I feel about Brett. I take great comfort in the fact that if Paul (of all people!) never got to a state of being un-perplexed, then I can be certain I'll never arrive there—and that's okay— because, like Paul goes on to say, "We do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but what is unseen. For what is seen is temporary, but what is unseen is eternal.” (2 Cor. 4:16-18) 

We can't see the eternal glory that Alisha and Brett are achieving here on earth but we can live "perplexed but not in despair" knowing they will be perfect and whole for all eternity.
