continual reminders

II Peter 1:12 “So I will always remind you of these things, even though you know them and are firmly established in the truth you now have.” God repeatedly reminds us of His great love for each of us.  He could just state a truth once, but He knows that we, as forgetful followers need continual reminders.  Spouses to each other, parents to children, family mambers to each other, grandparents to grandchildren etc. are continually expressing the same love thoughts to each other.  Why?  You tell me.
