Scripture
The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel of the glory of Christ who is the image of God.
Observation
Paul does not lose heart because his ministry is from God. He does not use deception or distort the word of God, but sets out the truth of the gospel clearly.
The gospel is veiled to those who are perishing because the god of this age has blinded the minds of unbelievers so that they cannot see the glory of Christ. The God who said “Let light come out of the darkness” is the one who puts the light into our hearts so that we can see the glory of Christ.
Application
The gospel has to be received as a revelation of God. Otherwise it is impossible for us to receive it.
I have seen people who have been opposed to the gospel suddenly get it and receive it. I have seen others in whom a light of revelation comes on for a short time and then is extinguished before the person receives Jesus.
Preaching to people, sharing the gospel, witnessing, is good. But we also need to prepare the soil for the gospel seed by fervent prayer for the person to be open to a revelation from God.
Prayer
Thank you Lord for making it possible for me to see your glory and to respond to the gospel. Please do this for my unsaved friends that their hearts may be enightened by you. Amen.
