The truth can be right in front of some people, and they still can’t see it because something is in the way blocking their view of God.
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 4:4 NIV
We can pray against whatever is in their way so that they can see the light of God. We can pray that they would see the truth without any obstacles or distractions interfering.
“Father, bind the evil spirits that are blinding the minds of the people around me. In the name of Jesus, I pray that they would be able to see clearly, to recognize who You are, and to give their hearts to You. Remove all hindrances the enemy would use to distract them from Your truth. Open their eyes, Lord, that they might see Jesus.”
