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. 2 Corinthians 4:4
When we’ve been praying and praying and praying for a breakthrough for someone, this is a good verse to keep in mind. I mean, when it’s laid out it all seems logical that someone – everyone – should receive Christ. But remember, unbelievers cannot see the way we see. I don’t say that to be mystical or super spiritual but it seems to be evident. Satan has blinded those who are not Believers.
Keep this verse in mind when praying for your unbelieving friends because ultimately it’s not what you say that will change their hearts; it’s the Spirit of Christ working through you to that person, and Christ removing the “blinders.”
