"Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. But small is the gate and narrow the road that leads to life, and only a few find it."
Matthew 7:13,14
I don't know about 5%, but I agree with your thinking. You being 14 have yet to feel the real temptation of the world yet. At the age 14 I could have said the very same claim. But now at 30 I have made mistakes that would send me to hell real quick. A Christian is not only some one who follows Christ, but will admit he is a sinner. By your statement your saying because your "good" your part of the elite 5%. A non sinner, perfect and strong enough to handle every temptation. This world has a big surprise for you!
C.S. Lewis wrote:
Imagine yourself as a living house. God comes in to rebuild that house. At first, perhaps, you can understand what He is doing. He is getting the drains right and stopping the leaks in the roof and so on: you knew that those jobs needed doing and so you are not surprised. But presently he starts knocking the house about in a way that hurts abominably and does not seem to make sense. What on earth is He up to? The explanation is that He is building quite a different house from the one you thought of- throwing out a new wing here, putting on an extra floor there, running up towers, making courtyards. You thought you were going to be made into a decent little cottage: but He is building a palace. He intends to come and live in it Himself.
