School bag on the roof is nothing. It is your rejection of God that will throw you under the bus.

Nobody has to do anything to you. God gave you the strength, in the kind of being that He made you to be, that you can reject Him if you want.

God wants you to accept Him, because He is the thing that holds you alive. If you reject Him, you reject your life and your self. God doesn't want that for you. But He also wants you to make up your own mind. He hopes you make it up the right way, so that you can live. But you have the freedom to make your decision as you wish.

Because of all this, no good Christian will attempt to force you to believe in God. No good Christian ever attempts to force anyone to believe in God. Good Christians tell the message about God, they attempt to convince, they call, they invite. But they don't force.

At the time your rejection is strong enough that there is absolutely no chance for you to accept God under any circumstances, God will know it. What He will do is unclear. He probably will let you die, then, giving you the thing you asked for - death - so that your sinning will be less than it would have been had you remained alive, so that you will be punished less in Hell for rejecting God.
