Romans 16:25-27 (K.J.V., all parenthetical statements mine)
Now to Him that is of power to stablish (Gk. ‘stenRIDZai’: ‘to make stable’, ‘place firmly’, ‘set fast’, ‘fix’: ‘to set ones face steadfastly’: ‘to strengthen’, ‘make firm’: ‘to render constant’, ‘confirm one’s mind’) you according to my gospel (Paul’s Mystery Gospel), and the preaching of Jesus Christ, according to the revelation of the mystery (Paul’s Mystery Gospel from Jesus Christ), which was kept secret since the world began, But now (to us today) is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith: To God only wise, be glory through Jesus Christ for ever. Amen.
Galatians 1:6-9, 11,12 (K.J.V., all parenthetical statements mine)
I marvel that ye are so soon removed from him (Paul) that called you (the foolish Galatians) into the grace of Christ (Paul’s Mystery Gospel) for another gospel (instead of Paul’s Mystery Gospel): Which is not another; but there are some that trouble you, and would pervert the gospel of Christ (Paul’s Mystery Gospel). But though we, or an angel from heaven (evil spirit), preach any gospel (other than Paul’s Mystery Gospel) unto you than that which we have preached unto you, let him be accursed. As we have said before, so I say again, If any man preach any other gospel (other than Paul’s Mystery Gospel) unto you than that ye have have received (from Christ to Paul and then them, and by implication to us today) let him be accursed.
But I certify you, brethren (brotherhood), that the gospel (Paul’s Mystery Gospel) which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelation (not the previous revelation in the Old Testament, because it was a progression of revelation over 1600 years with 39 human authors whom God controlled their minds as He revealed His word to man in their writ) of Jesus Christ.
Ephesians 6:15, 19 (K.J.V., all parenthetical statements mine)
And your feet shot with the preparation (Gk. ‘hetoimaSIA’ ‘the act of preparing’, ‘the condition of a person or thing so far forth as prepared’, ‘preparedness’, ‘readiness’, ‘readiness of mind’, ‘with the promptitude and alacrity which the gospel (Paul’s Mystery Gospel) produces.) of the gospel of peace (Paul’s Mystery Gospel).
And for me (The prayers he besought of the Ephesian Saints in verse 18), that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel (Paul’s Mystery Gospel).
