This is one of those Sundays where the verb 'to bless' has a critical role. And that, in itself, is a good reminder. In the end, it's God, the Lord of heaven and earth, who defines what that word means. God blesses in the way that he wants to bless.
Someone might point out that there are times when someone could be said to be blessing God, but that structure and its greater context doesn't put the focus on the person doing it. It is critical, though, to understand and believe what God is able to do. God is still the focus, whether we bless God or God blesses us.
The word 'mercy' is almost like blessing. Mercy implies showing compassion in some way. A blessing is more general, but that's not a bad thing. It also ultimately depends on a gracious and compassionate God. But how that blessing looks DOES NOT MATTER.
That's why Jesus can say things like, "Blessed are the poor in spirit." You wouldn't think that anything great will come to them. You might even considered them to be accursed. But you're not in charge.
It's extremely comforting to know that God is in charge of words like blessing ... holiness ... and forgiveness.
And it's just as comforting to know that he gives them out in special places and in special ways.
And it can take just a Sabbath Day's journey to get there.
