"Abscribe to the Lord..." the NRSV begins. I'm told by Robert Alter's Book of Psalms, that this verb means "to give" or "to grant." The Psalm begins by speaking to the heavenly court (a group that modern day Christians don't talk about much) telling them to grant praise to the Lord, and ends with the prayer that the Lord will give us strength and wellbeing.
We cannot see the invisible God but we can see the impact that God has on earth and within our community. Last week, in the reading from Acts 2, we remembered how this presence was described by the witnesses at Pentecost.
