For God, who said, "Let there be light in the darkness," has made this light shine in our hearts so we could know the glory of God that is seen in the face of Jesus Christ. We now have this light shining in our hearts, but we ourselves are like fragile clay jars containing this great treasure. This makes it clear that our great power is from God, not from ourselves. (2 Corinthians 4:6-7 NLT)
And even if our gospel is veiled, it is veiled to those who are perishing. The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God. (2 Corinthians 4:3-4 NIV)
"I was sought by those who did not ask; I was found by those who did not seek me. I said, 'Here I am, here I am,' to a nation that did not call on my name. (Isaiah 65:1 CSB)
