2 Corinthians 4:3-4 3But if our gospel be hid, it is hid to them that are lost: 4In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them. (2 Cor. 4:3-4 KJV)

The Apostle Paul and his co-workers have not failed to declare the glorious gospel. It is his prayer that the light of the glorious gospel, as a bright noonday sun that shone on that blessed day in his life on the way to Damascus, that restored the image of God in him, may so shine to others. Given to understand the truth, gloriously saved en route to heaven, he felt the burden that others may also be saved.
