Charles Spurgeon
The true minister of Christ feels impelled to preach the whole truth, because it and it alone can meet the wants of man. What evils has this world seen through a distorted, mangled, man-moulded gospel.

And even if our gospel is veiled, it is veiled 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
