God s Word is true. Praise the LORD we can live forever with him. Now, all you have to do is to believe God s word. God does not damn anyone. You damn yourself when you refuse to accept Christ - you close the door on eternal life.
Natural death is final, judgement is sure.
You might want to wait until your married, or older or established or whatever. God knows your future and he is calling for you now. The choice is yours. God does not make you accept his gift of salvation. He has given man the free will of choice.
