There is no way to access the wisdom of God except through Jesus. Until a person receives Christ, he is missing the only source of true wisdom. Men and women are not able to receive the wisdom of God, but those who submit themselves to God have access to the wisdom of God on their own, through the Holy Spirit. We must be dependent upon the Holy Spirit to receive the wisdom of God in our lives.
A Christian who has not received the Baptism of the Holy Spirit can have some revelation knowledge, but it will be limited. One of the greatest evidences that an individual has received the Baptism of the Holy Spirit is the tremendous amount of God's wisdom that becomes available to him.
The truths of the Gospel, and the power of God that these truths release, can only be given through the anointing of the Holy Spirit. Human wisdom, regardless of how eloquent it is, cannot convey the life of God. Much of the preaching of the Gospel today is done in man's wisdom. It's impressive to the carnal mind, but it leaves the spirit starving for the touch of God. The greatest need among ministers today is not to have more of the world's education, but to receive the revelation knowledge of the Holy Spirit. Only words spoken by the Spirit of God can reach the spirit of man. Spiritual thoughts have to be spoken with spiritual words (1 Corinthians 2:13).
