"Will you be angry with us forever?
Will you prolong your anger
through all generations?
Will you not revive us again,
that your people my rejoice in you?"
Did you ever have those fears as a kid? You messed up royally. Intentional or unintentional, it didn't matter. The harm had been done and there was no way that life could ever get back to normal. Your mom and dad would be angry with you until the end of time.
I had a very strong, black-and-white conscience when I was a kid, and whenever I messed up I felt like life with my parents was over. It wasn't because of them; it was me. I felt like my "iniquities" would separate me from their love forever. To me, there was no way they could trust me or accept me back into their arms again.
The strange thing was they always did. As much as my mind reeled with all of the reasons I should just pack up my bags and leave, move in with my friend, or just mutely walk through the rest of my days (actually, my parents might have enjoyed that!) my parents always kept loving me. It was uncanny! How could they keep loving me?
In the verses above the Sons of Korah asked these same questions of God, they later in the chapter give us the answer to why God keeps loving us and bringing us back in.
"Love and faithfulness meet together;
righteousness and peace kiss each other.
Faithfulness springs forth from the earth,
and righteousness looks down from heaven.
The Lord will indeed give what is good,
and our land will yield its harvest.
Righteousness goes before him
and prepares the way for his steps."
"Love and faithfulness meet together." God loves us and is faithful to us His children. He will not be angry with us forever. In fact, He longs for us to return to Him.
