2 Corinthians 7:15
And he has great affection for you when he remembers how obedient all of you were [i.e., obedient to his or Paul's instructions to the church], and how you welcomed him with fear and trembling [i.e., with a respectful, submissive spirit].
2 Corinthians 10:6
[And we are] prepared to punish all disobedience when your obedience is complete. [Note: This probably refers to the Corinthian church dealing with its unrepentant member. See I Cor. 5:3-5].
So then, my dear ones, just as you people were always obedient [to my teaching] when I was there with you, so now, in my absence [also], be [obedient] all the more. [Continue to] complete your own salvation [i.e., by living faithfully to the end. See Rom. 13:11] with fear and trembling [i.e., with a reverent and submissive spirit],
2 Thessalonians 3:14
And if any person does not obey our instructions, [given] in this letter, you should take note of him so that you do not associate with him, in hope that he will become ashamed [of his conduct].
I am writing you, confident that you will be obedient [to my requests], and I know that you will do even more than I am asking [of you].
Whosever sins you forgive, they will be forgiven [by God]. And whosever sins you do not forgive, they will not be forgiven [by God]." [Note: Actual forgiveness would result only when people responded, by faith, to the Gospel message. See Acts 2:37-38].
