The phrase eternal life occurs over 20 times in the Scriptures. In contrast the phrase life eternal occurs less than 8 times, and everlasting life over 10 times.

John 10:28 “And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.” 1 John 5:13 “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.”
