Because of this [i.e., their improper partaking of the Supper], many people among you are weak and ill, and a number have fallen asleep [i.e., died]. [Note: While most commentators view this judgment as physical, there is a distinct possibility that it refers to spiritual sickness and death].
[But] if we confess our sins [to God], He is faithful [to His promise] and righteous [in His judgment], and will forgive us of those sins and cleanse us from all of our wrongdoing.
So, remember where you have fallen from and repent [i.e., change your hearts and lives] and do the things you did at first [i.e., when you were first converted], or else I will come and remove your lamp stand from its place [i.e., I will not permit the congregation to survive], unless you repent.
