The next time you have to listen to someone disparage the one he calls "The Old Testament God," you might point out that, despite human intransigence that God kept loving them and caring for them. For example:
The Lord is gracious and merciful, slow to anger and abounding in steadfast love (v.8)
This grace, mercy, and steadfast love is not restricted to just a few:
The Lord is good to all, and is compassion is over all that he has made (v.9).
Good to all--all who are falling, all who are bowed down. God's care includes basic necessities, like food, and also more than necessities.
We can be further reassured or perhaps not when we read that the Lord is just in all his ways. We do read some qualification of God's qualities in verses 19 and 20.f
We are part of a long line of worshippers who have praised God, learned about God's care, and told others:
My mouth will speak the praise of the Lord,
and all flesh will bless his holy name foever and ever.
