Any teaching about grace that discounts the requirements of obedience for eternal salvation, Heb 5.9, denies the “true grace of God” 1 Pet 5.12.
The Lord has always required full #obedience of his people. “The Lord will deliver them over to you, and you must do to them exactly as I have commanded you” Deuteronomy 31.5 CSB.
Oswald Chambers wrote, “Sometimes there is nothing to obey and our only task is to maintain a vital connection with Jesus Christ.” The truth of the matter is that we maintain our vital connection with Jesus Christ by #obedience. There is no other way.
Man ignores the plain truth of Scripture, when it does not agree with his theology: “Whereas we have a hand in the process of sanctification and can affect it by our obedience or disobedience, God alone justifies us” (Tho. Constable). God says (in Romans!) that obedience results in righteousness, Rom 6.16 NASB.
“… Moses had predicted the arrival of a Prophet, and this Prophet was the Messiah (see Luke 24:19; John 1:19-28; 6:14). Not to obey (“hear”) this Prophet meant condemnation.” —W.W. Wiersbe
“Paul saw that if a man accepted the Gospel it could be said of him that he ‘believed’—a word he uses to mean to accept baptism and become a Christian … because the Gospel demanded to be believed since it was God’s word, to accept it could also be called ‘obedience’.” —A.R.C. Leaney, Letters of Peter and Jude, 28.
The Bible equates seeking God with obeying his commands. King Jehosaphat “sought the God of his ancestors and obeyed his commands” 2 Chr 17.4.
