My mouth shall speak the praise of the LORD: and let all flesh bless his holy name for ever and ever. Let all flesh bless his holy name - He is good to all, wants to save all, actually feeds and preserves all. And as near as שמר shamar is to שמד shamad, so near is he a Savior to those who stand on the brink of destruction, if they will look to him.
For the application of all this Psalm to the Church of Christ, see the analysis.
