Men suppress the truth. The problem is not in the facts, nor in our message, nor even in our presentation. The problem is that people don't want to hear the truth. This is very strange, since people are incredibly hungry for what only God can provide. She always has an excuse, has a mitigating circumstance, or changes the subject.
Nobody likes to be in the wrong.
People like even less to be in the wrong in the eyes of somebody important. When unbelievers are told that they stand guilty before Almighty God, it is therefore not surprising that they fight against that reality, even though acknowledging their guilt and need is the only way to the healed relationship with God that their heart craves. People also don't want to hear the truth about God because they love their own self-will, even though it leaves them empty inside. They would rather be in control of their own lives than deal with what the holiness of God requires of them. The second reason why people don't respond to the gospel is that Satan blinds them.
