*Gospel: Euaggelion (yoo-ang-ghel'-ee-on); Word Origin: Greek, Strong's Greek Dictionary #2098. 1. a reward for good tidings. 2. good tidings.
People’s New Testament Commentary:
Romans 1:16: God's plan of salvation in Christ. Its three great facts are the death, burial, and the resurrection of Christ. It is the power of God unto salvation. The gospel is God's only appointed means of salvation. The name of Jesus Christ "is the only name whereby we must be saved [Acts 4:12]." All God's saving power is manifested through the gospel.
Easton's Bible Dictionary:
A word of Anglo-Saxon origin, and meaning "God's spell", i.e., word of God, or rather, according to others, "good spell", i.e., good news. It is the rendering of the Greek evangelion, i.e.: "good message." It denotes "the welcome intelligence of salvation to man as preached by our Lord and his followers. It was afterwards transitively applied to each of the four histories of our Lord's life, published by those who are therefore called 'Evangelists', writers of the history of the gospel (the evangelion). The term is often used to express collectively the gospel doctrines."
Vine's Dictionary of NT words:
(Noun and Verb: to preach) (A-1, Noun, 2098, euangelion) Originally denoted a reward for good tidings; later, the idea of reward dropped, and the word stood for "the good news" itself. The Eng. word "gospel NTB," i.e. "good message," is the equivalent of euangelion (Eng., "evangel"). In the NT it denotes the "good tidings" of the Kingdom of God.
"There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus."

*The King James Bible...
I know that there will be some who will object to my usage of the King James Version (or, also called the Authorized Version) for my scriptural quotes herein, which was first published in 1611 A.D. I am fully aware of the controversy over Bible translations, and especially over the Hebrew and Greek source texts that are either feared, rejected, or accepted. My personal study choices are three English versions, namely the original William Tyndale Version of the early 1500's A.D., the King James Version of the early 1600's A.D. (which was updated with more modern spellings in the mid 1700's A.D.), and the more recent J.P. Green literal Version (of the mid 1900's A.D.: which is found in the Hebrew, Greek, and Aramaic Interlinear Bible − which also has the very helpful Strong's Hebrew and Greek Dictionary numbering system, which allows anybody to become familiar with the original languages). These three English versions, for the most part (except for some minor details − as outlined meticulously in J.P. Green's introductions), share the same Greek source texts of the New Testament with each other, and the same Hebrew and Aramaic texts of the Old Testament. And for that reason, it becomes helpful to compare these three English renderings with each other . . . I will give my full reasons of my biblical choices in my upcoming writing, entitled: 'The Bible is Not a Buffet.'
