Jesus told them, “If God were your Father, you would love me, because I have come to you from God. I am not here on my own, but he sent me. Why can’t you understand what I am saying? It’s because you can’t even hear me!
John 8:42‭-‬43 NLT

We may have good intentions of witnessing the gospel of Jesus Christ and teaching people how to love and forgive. We may talk/minister to them for a long time, but some of the people we talk to can’t receive anything we’re saying. Don’t get frustrated with them. 2 Corinthians 4:4 says, Satan, the god of this world, 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.

While we’re speaking, they can’t comprehend what we’re saying because their minds have been blinded.

We may want them to do better, have better, and be stronger, but until their minds are renewed with the word of God (Rom. 12:2), they’ll never fully take advantage of what Jesus made available to us. For now, we can use our authority to remove the demonic strongholds from their minds (Luke 10:19) and pray they receive a correct revelation of what we’re trying to convey. Secondly and simultaneously, cast their situation to God. We shouldn’t be carrying their cares on our shoulders. That’s what causes frustration. Give it to God and move on.
