The Main Message of the BIBLE is that God has provided a Wonderful Plan of Salvation; one that:
"For all have sinned and come short of the glory of God" (Romans 3:23); "If we say that we have no sin, we deceive ourselves, and the truth is not in us" (1 John 1:8).
"As by one man sin entered the world, and death by sin; and so death passed upon all men, for that all have sinned." (Romans 5:12); "For the wages of sin is death." (Romans 6:23).
"Every one of us shall give account of himself to God" (Romans 14:12); "How shall we escape, if we neglect so great salvation" (Hebrews 2:3).
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" (John 3:16).
"Not by works of righteousness which we have done, but according to His mercy He save us" (Titus 3:5); "By grace are ye saved through faith, and that not of yourselves; it is a gift of God not of works lest any man should boast" (Ephesians 2:8-9).
"If thou shalt confess with thy mouth the Lord Jesus, and shall believe in thy heart that God hath raised Him from the dead, thou shalt be saved." (Romans 10:9)
