The testimony of God is to know Jesus and Him crucified. Also to walk humbly before God and man. God will demonstrate through his Spirit who He is and His power. So, that our faith will stand in the power of God. For the wisdom of God is perfect. God-ordained His wisdom before He made the world. No man knows the wisdom of God. He has prepared all things for those that love Him. The Spirit of God reveals god’s wisdom to those that love Him. We have to receive the spirit of God to know those things that God freely gives us. The Spirit of God compares all of man’s wisdom against Spirit God’s. Man thinks that God’s testimony is foolishness, because they are spiritually discerned. God is the judge of all things. So, who can instruct God. But thank God we have the mind of Christ.
