In today's Gospel reading from Matthew 11, Jesus gives praise to the Father, acknowledging that knowledge of the Kingdom has been hidden from "the wise and the learned" but revealed to "the childlike." A reminder for us to always remain childlike.
In the first reading from Isaiah 10, the Lord acknowledges that he allowed Assyria - even "sent" Assyria - to punish Israel. But the Assyrians thought they were doing all this on their own. Little did they know this was all part of God's plan.
I certainly don't pretend to know the mind of God. Anyone who claims to know that fully is a fool. We often don't know why God allows certain things, especially tragedies, or what would appear to us to be tragedies. But I think we can count on one thing: God can bring good of anything and everything. (See Romans 8:28) So whatever happens, let's trust that God has plan, and it will all work out in the end.
Father, we put our trust in you, even though we may have no idea why things happen. Thy will be done. Amen.
