"I have come to bring a sword" is not a covenant. If you would drop the concept (and word) 'covenant', we can have a conversation. Otherwise, you're off in left field.
you have it back to front,
all believers will have a sword that Pearce's there soul, which then means they are under a new covenant.
A covenant is contract or a will.
How much more of a contract or a will be, when a sword penetrates your soul can this be.
Each covenant throughout the bible establishes the basis of a relationship, and conditions.
Then theres the consequences of not honouring those conditions.
So how much of a relationship is the sword that Pearce's your soul.
And how much of a condition can that be.
And how much of a will can that be
And Jesus will come back to settle disputes between all nations including those who have that sword.
As he will watch all nations strike there plough shares with there swords.
Then he will judge all nations.
Obviously they must be the swords that penetrate there soul.
Obviously you have missed the covenant that Christians are under 😊
