2Instead, we have renounced secret and shameful things, not acting deceitfully or distorting the word of God, but commending ourselves before God to everyone's conscience by an open display of the truth.
4In their case, the god of this age 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.
6For God who said, "Let light shine out of darkness," has shone in our hearts to give the light of the knowledge of God's glory in the face of Jesus Christ.
15Indeed, everything is for your benefit so that, as grace extends through more and more people, it may cause thanksgiving to increase to the glory of God.
