Are blind Christians oxymorons?

Can Christians be blind to spiritual things? In 2 Corinthians chapter 4, the Apostle Paul characterizes the whole scheme of salvation by making a comparison to blindness. In verse 3 of 2 Corinthians 4, Paul says, "If our gospel be hidden, it is hidden to them that are lost." In other words, if as we preach the gospel of Jesus Christ it is hidden, the ones to whom it is hidden will be those that are lost. Why? Because they are those in whom the God of this world has blinded the minds. The reason men do not understand God or God's truth is because they are spiritually blinded by the God of this world, lest the light of the glorious gospel should shine unto them.Later on in verse 6, Paul says it is we Christians who have seen the light. God has commanded in us that light should shine out of darkness. But in the case of unbelievers, they are in darkness, their minds blinded by the God of this world to prevent the light of the gospel from shining unto them. And thus it is hidden to them. When salvation comes along, it opens the eyes of the soul or the spirit to understand light and to comprehend God's truth.This is clearly illustrated by Paul when he was talking to Agrippa in the twenty-sixth chapter of Acts. He says this, "I came to open their eyes and turn them from darkness to light." That was Paul's mission, to take spiritually blind people and give them spiritual sight. Now the scriptures teach us that it is only those who know and love Jesus Christ who have spiritual sight. There are a lot of people in the world who are religious and think they see. The Pharisees did. They were super religious. And they thought they had everything pigeonholed. They thought they could see and comprehend every spiritual truth in existence. They thought they knew everything And in fact they knew nothing. They were totally blind.

So based on the word of God, Christians cannot be spiritually blind. People can claim to be a Christian but can be merely religious and go to church. The Bible teaches us about being swayed to and fro. Too many people in the Church are allowing themselves to be swayed by the popular opinion and are totally deceived (remember that Satan is a deceiver and liar). They are being led down a path they shouldn't be on. I pity these people who have been blinded by the devil, yes he does exist and he doesn't have a red cape or a pitchfork). Many people who profess to be a Christian are headed for hell. What is my point in all of this? Examine yourself to make sure you are in the faith. Don't rely on feelings. Rely on the Spirit of God communicating with your spirit that you are in fact a true believer.
