The Bible teaches emphatically that once a person is saved, then they are saved eternally. The God, who cannot lie, promised us that our salvation would be forever.
"And whosoever liveth and believeth in me shall never die. Believest thou this?"
"In hope of eternal life, which God, that cannot lie, promised before the world began;"
"Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life."
"All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out."
