Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.  Matthew 7:13-14

How do I get on the highway to hell?  A better question would be, how does one get off of the highway to hell?  Unless one has been born again, he/she is already on it.

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 3:18

He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him (God) a liar; because he believeth not the record that God gave of his Son.

And this is the record, that God hath given to us eternal life, and this life is in his Son.  He that hath the Son hath life; and he that hath not the Son of God hath not life.

These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.  I John 5:10-13

Who hath ascended up into heaven, or descended? who hath gathered the wind in his fists? who hath bound the waters in a garment? who hath established all the ends of the earth? what is his name, and what is his son’s name, if thou canst tell? Proverbs 30:4

…let the word of Christ dwell in you richly…
