Great book. The two verses that hit me the most were near the end of the book:
Ecclesiastes 10:10“If the ax is dull, and one does not sharpen the edge, then he must use more strength; but wisdom brings success.” Ecclesiastes 12:13-14
“Let us hear the conclusion of the whole matter:
Fear God and keep his commandments, for this is man’s all. For God will bring every work into judgement, including every secret thing, whether good or evil.” Will commit both of these to memory.
