If you're not sure the Bible is the word of God watch:

How to know you're saved:

Jesus Christ is God who has come to earth from heaven in the flesh. He died as a sinless sacrifice for the sins of the whole world to save you from eternal hell, the punishment for your sin. He was buried, then resurrected and is now in heaven. John 3:16: “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.” Romans 10:9: “That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
John 10:28: "And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand."
God wants to forgive you, but you have a choice: Either choose this evil world and be punished along with it, or choose to submit to the will of God and be saved. Your own deeds, no matter how good you think they are, can NEVER justify you. You're corrupt and need to be saved. Romans 5:9: “Much more then, being now justified by his blood, we shall be saved from wrath through him.” Salvation is by grace through faith in Jesus Christ, in what HE did for you. Only He can wash away all of your sins with His blood. Salvation is a gift, it can't be earned. Do you choose the righteousness of God or your righteousness? Heaven or hell?
Eph. 2:8-9: “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.”
