What does the Bible say about God's control over our plans?

Proverbs 16:9 succinctly states, 'A man's heart deviseth his way: but the Lord directeth his steps.' This verse encapsulates the sovereign control of God over human affairs. While individuals may strategize and make plans based on their desires and understanding, it is the Lord's purpose that prevails. In the case of Paul, although he planned to undertake a Nazarite vow, God had other intentions that ensured His glory and the spread of the gospel. This serves as a profound reminder that even when our plans do not materialize as anticipated, God’s sovereignty doesn’t falter; instead, He orchestrates circumstances for His ultimate purpose.
