Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst G5111 not G3766 bring against him a railing accusation, but said, The Lord rebuke thee.
The KJV translates Strong's G5111 in the following manner: durst (7x), dare (4x), be bold (4x), boldly (1x).
The KJV translates Strong's G3756 in the following manner: not (1,210x), no (147x), cannot (with G1410) (57x)
Moses Trembled and was afraid to look upon Elohim, He from fear, dared not look
Michael dared not bring a accusation
Not convinced, then read the verse in its context, brutish men speaking evil of things they don't understand, Yet Michael who did understand dared not say anything against satan, and said the Lord rebuke you
In Summary
you want people to believe, that the Pre-Incarnate JESUS who you believe was is and will always be Michael the Archangel, who dared not, bring a accusation against satan is God Almighty.
LOL
I'll Pass!!!
What is important is that you believe that Jesus is the eternal Son of God.
That He became human and died for our sins.
Through that action (by God alone) we can repent of our sins and be saved.
Arguing about who Jesus was before He became incarnate is actually useless.
Some want to argue that Michael is an eternal being. And there is scriptural evidence.
Others want to say He is a created being. One of several archangels.
But that aligns more with the Books of Enoch which are Catholic forgeries.
I just don't see the point in arguing the matter.
