Psalm 86:15 But You, O Lord, are a God full of compassion, and gracious, Longsuffering and abundant in mercy and truth.
Just as precious as a child is to their parent, so we are to God. He cares for us with tender loving compassion.
We can describe His mercy toward us as being rich and plentiful because there seems to be no end to it and it is refreshed every day.
When we do go astray He will try to persuade us back time and time again just as a true friend would do.
This is all so because God has chosen it to be this way!
