...written to believers? Just finished this book through the lens of John MacArthur's study Bible and he claims that the use of sinners (4:8, 5:20) is always in reference to the unregenerate. Problems with this, particularly 5:20...the use of "turns them BACK...". How can this be an unregenerate, and how can he immediately in verse 7 tell these same "sinners" to submit to God and resist the devil, and then shortly thereafter in v. 11 address not judging a "brother"? Another part that sent up red flags is 4:5 "Or do you think that the Scripture sayss in vain 'The Spirit who dwells in us yearns jealously'". His claim is the Spirit here is not to be understood as the Holy Spirit, but the human spirit of an unbeliever confused. Thoughts on these chapters? Brethern is used throughout and the book is addressed to believers, no?
