No matter how smart or intelligent someone is, there is no way to figure the ways of God by natural means. When someone is told about the ways of God through mans ideologies, it will seems to be nothing but foolishness and fantasy. Our carnal minds are programmed to view the ways of God through the lens of the worldly knowledge and traditions of man.
The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. - 1 Corinthians 2:14
You can only learn the things of God via the Holy Spirit who transforms the mind. The natural man cannot receive the things of God.
The Early Church understood that spirituality is not attained by receiving certificates, diplomas, titles, and offices at some college or seminary. These are man-made ideals.
And even if our gospel is veiled, it is veiled only to those who are perishing. In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God. - 2 Corinthians 4:3-4
