1.)     I don't consider myself a sinner.  Aren't people who commit serious crimes sinners?

Romans 3:10 - As it is written, There is none righteous, no, not one: 

James 2:10 - For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.

2.)    I have lived a good life and done good works. Isn't that enough?

Ephesians 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.

Titus 3:5 - Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;

3.)    A loving God would send someone to hell? 

(Because God loved us, He allowed His son to suffer the punishment we deserve.)

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.

II Corinthians 5:21 - For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.

(God does not send anyone to hell; a sinner who does not believe in Jesus' sacrifice for sin sends himself to hell.)

John 3:17-18 - For God sent not his Son into the world to condemn the world; but that the world through him might be saved.  He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.

John 3:36 - He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
