The god of this age has blinded the minds of unbelievers so they cannot see the light of the gospel of the glory of Christ, who is the image of God.-2 Corinthians 4:4, BSB
Why is the belief of atheism so dangerous for the atheist? The reason it is so dangerous is that Satan blinds them and convinces them that God is not real, which keeps the person from pursuing spiritual truth, like the afterlife and the Creator of the universe. That type of persuasion keeps them in the dark.
When a person doesn’t believe that something is real, they won’t try to investigate it to see if it is true. If they presume to seek the Bible for evidence, they go about it with complete doubt making it useless and a waste of their time.
The devil persuades these people from even thinking about searching for God through the Bible by luring them away through worldly lust of all kinds. The devil tells them, “if you become a Christian, you cannot enjoy your sinful desires that you live for and must give them up.” He will keep them from the truth, which will send them to hell because they won’t seek redemption from their state by asking Jesus Christ for salvation.
Imagine that you are in a big boat and you come across a man whose boat capsized and now is in the water, which is teeming with sharks. You offer to save the man. He gives you a weird look and says to you, “save me from what?” You reply, “Huh…don’t you know that you are in danger?” The man then replies, “I don’t need any saving.” Then you say, “Are you serious?” “If you don’t get into my boat, you will be eaten by sharks.” To your amazement, the man replies, “Sharks don’t exist and you are deluded that I’m in such trouble. Leave me alone and go tell this fairy tale to someone else. I’m fine where I am at.”
Friend, don’t be like this atheist. Believe in the Lord Jesus Christ and what He did for you. He died on the cross and rose from the grave on the third day. Ask Jesus to forgive you of your sins, and he will forgive you and give you eternal life.
