1 Corinthians 1: 25 Because the foolishness of God is wiser than men, and the weakness of God is stronger than men.
The Apostle Paul was speaking to the church at Corinth, and encouraging those who were believing in Christ in these scriptures. They were ‘going against’ what the world was preaching or questioning; stepping out in faith and seeing God there. 22 For Jews request a sign, and Greeks seek after wisdom; 23 but we preach Christ crucified, to the Jews a stumbling block and to the Greeks foolishness, 24 but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. Paul was very well educated and easily could have rested on his worldly wisdom and preached from that authority. He also realized that was what the world expected, and the power of the Gospel lied in the power of what Christ had done at the Cross. 17 For Christ did not send me to baptize, but to preach the gospel, not with wisdom of words, lest the cross of Christ should be made of no effect.
Why can’t God use you too? Do you believe in the power of the Cross; and the Gospel of Jesus Christ as the Good News that He has come to save the world? The faith that you have will go against the ‘proof’ or ‘tangible’ that the world demands. But you don’t have to rest on your wisdom as Paul was speaking of; just rest on the message that Christ brings. Your testimony and the change that Christ has brought into your life is the power that God has given you. 27 But God has chosen the foolish things of the world to put to shame the wise, and God has chosen the weak things of the world to put to shame the things which are mighty. Do not ever be afraid to share your faith from the feeling of fear from a lack of wisdom. God has given you the ability for just the right word at just the right time for those He has called. Your faith may fall on deaf ears sometimes, but to not be discouraged. 18 For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.
