" For God so Loved the world, that He sent his only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life." John 3:16 (Verse is sometimes called the Bible in a Nutshell)

Roman's Road (Promise of Salvation)
Rom 3:10 "As it is written, There is none righteous, no, not one"
Rom 3:23 "For all have sinned, and come short of the glory of God"
Rom 5:12 "Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned"
Rom 6:23 "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord."
Rom 5:8 "But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us."
Rom 10: 9-13 "That if you shall confess with your mouth the Lord Jesus, and shall believe in your heart that God has raised Him from the dead, you will be saved. For with the heart man believes unto righteousness; and with the mouth confession is made unto salvation. For the scripture says, Whosoever believeth on Him shall not be ashamed. For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. For whosoever shall call upon the name of the Lord shall be saved."

Best place to start reading the Bible: Book of John, then read the books of Matthew, Mark and Luke..(then whatever)

The Old Testament points to Christ, the New Testament reveals Christ.
