Yesterday’s Gospel reading was one of my favourite – it’s from where we get the peace saying in the Mass. There is more to the passage, of course, but what one can essentially take from it is the power and strength of the peace that God brings, in this case, via Christ.
The point of Jesus’ pronouncement is to separate the Holy Spirit’s peace from the superficial and temporary peace one encounters with worldly goods. God wants us to find peace, but He also wants us to find the right kind of peace and not be so bogged down or obstructed by material wishes that we cannot make time for God or for others.
Yes, we can everything from this: the big message that without God, we are left in a level of peace that will forever be unfulfilling for us.
I wouldn’t say there is a specific reason why this is one of my favourite Gospel readings. It in itself brings a sense of peace; and the fact that God is here, and we are made aware that His is the peace available forever to us is something memorable in itself.
