"As soon as we saw Nathaniel, we feared that consumption had marked him for the grave. The hectic flush was upon his cheek, yet we hoped and prayed that the Lord would spare him, that his talent might be employed in the cause of God. But the Lord saw fit to order otherwise. LS 147.1"
"And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me."
The passage reflects the theme of God's will being different from human desires, even when those desires are for service to God. The acceptance of weakness and infirmity aligns with the sentiment in 2 Corinthians 12:9.
