What makes the gospel appealing to the unbeliever?
What make a life raft appealing to a drowning man? What makes water appealing to a man who is wandering in the desert?
If I put on a fireman's turnout gear and ran into your house saying, "Don't be afraid, I'm here to help you", you'd think I'd lost my mind.
However, if your house were on fire and you were trapped inside and I came in and said, "Don't be afraid. I'm here to help you", you would feel tremendous relief.
In the same way, the Gospel makes very little sense to the lost until they understand why they need the Gospel. The Good News is not good news unless the lost first understand the bad news of God's wrath.
In my case, I never thought twice about the Gospel until one night, on a little boat off the coast of St. Bart's, I read about Isaiah.
When Isaiah came face to face with God's holiness, he came completely unglued. I can almost picture him running about the sanctuary looking for a place to hide from God, like Adam and Eve did when they realized they were naked before God.
Isaiah wasn't just some guy off the street. He was God's own man. He had been ordained and set apart for God's service by God, Himself.
It wasn't until I realized that, if God's holiness is so great that His own prophet considered His own sinfulness before God and trembled, then how on Earth must God see me?
I started to really examine myself and the sins I'd committed in my lifetime and all of the ways that I had broken God's laws and I realized that I was in deep, deep trouble.
It was then and only then that the ground of my heart was ready to receive the seed of the Gospel.
