1 Corinthians 1:18-29
Hebrews 11:1 describes faith as "the assurance of things hoped for, the conviction of things not seen." Another way of saying that is "knowing that God will honor His Word."
Reason can be the enemy of faith, because it attempts to "trump" trust in God by encouraging us to rely on human intellect. This kind of logical thinking places confidence in man, but since we are not all-knowing or all-powerful, it leads to insecurity and worry.
All the while, God waits patiently for man to acknowledge his need of a Savior and then respond in faith. Reason says, "I can do it." Faith says, "With God, all things are possible" (Matt. 19:26). Reason says, "Hurry and get yours before it's gone." Faith responds, "My God will supply all your needs according to His riches in glory in Christ Jesus" (Phil. 4:19). Reason wrings its hands and says, "There has to be a better way!" Faith looks at Jesus and hears Him whisper, "I am the way, the truth, and the life" (John 14:6).
God's Word states that the message of the cross is foolishness to those who are perishing. It makes no sense whatsoever to them because Satan has blinded their eyes to the truth. But to us who are being saved, the Gospel is the very power of God (1 Cor. 1:18).
In 1 Corinthians 1:19, God says, "I will destroy the wisdom of the wise, and the cleverness of the clever I will set aside." Those who are of the world may seem to have the upper hand now, but a time will come when they will wither like grass. Only those belonging to Christ possess eternity. We need to lovingly share this truth with others.
