I have had some snags in life recently, in November I lost my dear sister. Yes God helps us with grief, however we tend to hold on to it. In this time the Lord reminds me of Philippians 4:8
whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable - if anything is excellent or praiseworthy - think on these things
This turns me around, knowing that sadness pulls us down. Joy picks us up, singing renews our spirit - try it, you'll like it
