To the prophet Isaiah, the plans and purposes of God were formulated outside of His creation–in other words, without the help of human wisdom.
Isaiah says that God’s hidden plans and purposes work in behalf of people who wait for God to work His will–people who place their faith and trust in God.
The Apostle Paul quotes this verse in 1 Corinthians 2:9 to contrast human wisdom with God’s wisdom: “That is what the Scriptures mean when they say, No eye has seen, no ear has heard, and no mind has imagined what God has prepared for those who love him” (I Corinthians 2:9).
But Paul raises the stakes by indicating that God not only works for those who trust Him, but He has big plans for His people!
And, Paul also states that what was incomprehensible is now understood because it is revealed to those who have received God’s Spirit: “But it was to us that God revealed these things by his Spirit. For his Spirit searches out everything and shows us God’s deep secrets” (I Corinthians 2:10).
In other words, God’s plans and purposes are not understood through human wisdom or philosophy, but only by God’s own Spirit, who alone can reveal His thoughts to His people. And God has graciously given his Spirit to his people so they can know the big plans He has prepared for them.
And God will, indeed, reveal to you His big plans for you, if only you trust Him and and wait for Him to do His work through you.
“But they who wait for the Lord shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.” (Isaiah 40:30, ESV).
