Ephesians 5:17. “Wherefore be ye not unwise, but understanding what the will of the Lord is.”
I love the contrast here. Don’t be foolish. Foolishness consists in not knowing what the will of the Lord is. Wisdom consists in knowing His will.
How simple is that? Proverbs 9:10 “The fear of the Lord is the beginning of wisdom and the knowledge of the Holy One is understanding.”
A wise person is one who spends time in the Word, who studies and seeks to understand what God is saying. When we do that, we will find His will. In seeking and doing His will, we grow in wisdom.
We make knowing God’s will so complicated, when in fact it is clear. We just need to be in the Word.
