Ro 14:11 For it is written, As I live, saith the Lord, every knee shall bow (2578) (5692) to me, and every tongue shall confess (1843) (5698) to God.
Do the two differences in "Voice" within the same verse (Active and Middle) indicate Choice in "confession" and the lack of Choice in "Bowing"?
5784 Voice-Active The active voice represents the subject as the doer or performer of the action.
5785 Voice-Middle The middle voice indicates the subject performing an action upon himself (reflexive action) or for his own benefit.
The "bowing" aspect or submission denotes submission but not in a "volitional" sense. This seems to be more in line with "reaping what we sow".
This conclusion suggests to me that while all people are responsible to God, only those who choose to do so will make confession to Him.
Thus, His judgment is made clear to all people.
