An eye for an eye is just, how can it not be?
A life for a life is just how can it not be?
Self defense is just.
However if we call on God to be just, we end up condemning ourself, because if we expect others to pay for their sins, surely it is also just that we pay for our own also, or how would it be just?
However Jesus teaches another way. Love your enemies, do good to those that hate you.
We have examples in the nt where the pharasiees went to stone Jesus, and Jesus somehow always managed to slip away. Again, it would of been just that Jesus killed them instead, in self defense, but Jesus shows another way.
Jesus answered, “
My Kingdom is not an earthly kingdom. If it were, my followers would fight to keep me from being handed over to the Jewish leaders. But my Kingdom is not of this world.”
In my opinion the Godly way for Israel to of acted would of been to fast, pray and turn to God, to deal with the situation rather then lean on their own military might.
We have examples in the ot, where God has put whole armies to sleep, when God steps in the war is over very quickly.
Here from revelations 13:10
10
He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints.
51With that, one of Jesus’ companions reached for his sword, drew it out and struck the servant of the high priest, cutting off his ear.
52“
Put your sword back in its place,” Jesus said to him, “for all who draw the sword will die by the sword. 53Do you think I cannot call on my Father, and he will at once put at my disposal more than twelve legions of angels?
Again Jesus shows us a different way.
The Israel / Hamas war is another earthly war, but those who are Christian should learn not to act this way.
1 Corinthians 5:12
12
For what have I to do with judging those also who are outside? Do you not judge those who are inside? 13 But those who are outside God judges. Therefore “put away from yourselves the evil person.”
The only advice i can give is to stay away from this whole topic, and work on loving others.
