Contrasting the difference between faith and our own wisdom is rather easy in the Bible. Take this passage in Proverbs 28:26a:
26 He who trusts in his own heart is a fool (NKJV)
In the Hebrew mindset, the “heart” was not the seat of emotions, but rather your knowledge, intellect and will (cf Proverbs 12:25; 13:12; 15:12,14a; ). So the Bible warns us in many places not to lean on our own wisdom or will. Rather, look to your Abba Father in faith – with absolute trust that He has you in the hallow of His hands. Nothing will reach you without going through Him. And nothing will take Him by surprise.
Don’t analyze everything to death. Don’t assume you have tomorrow—nor even today—totally figured out. Instead rely on our Father’s love for His children and for you individually. Count on His loving heart and tender mercies (Psalm 103:4, 118:1). Know that not only is He in control, He is always victorious.
Don’t forget, you are accepted in the Beloved (Ephesians 1:6), you are sealed with His guarantee of the glory to come (Ephesians 1:13-14), and nothing in Heaven or Earth can separate you from His love and your victorious future in Christ Jesus (Romans 8:35; Ephesians 1).
So as the Apostle Paul says: “…stand…” (Ephesians 6:13) in these uncertain times. But don’t stand trusting in your own wisdom and power. Stand by faith in Christ Jesus and by trust in your Abba Father.
NKJV Proverbs 3:5-6
5 Trust in the Lord with all your heart,
And lean not on your own understanding;
6 In all your ways acknowledge Him,
And He shall direct your paths.
