The lost are ignorant to the truth of the Bible. It cannot be understood unless we are Christians. In Acts it says, “And even if our gospel is veiled, it is veiled to those who are perishing, in whose case the god of this world has blinded the minds of the unbelieving so that they might not see the light of the gospel of the glory of Christ, who is the image of God” (2 Cor 4:3-5 NASU).
We will only be able to see the truth about Christ when God reveals it to us. He will not reveal His truth to us until we commit our lives to him. We do not become Christians on our own terms.
