Happiness is circumstantial. When life is good and things are turning out well, we are happy. When things go ‘pear shaped’ or ‘belly up’, we are “not happy Jan!” Joy is the fruit of knowing God’s love for us in Jesus. Nothing that you and I experience can change God’s heart towards us, or cancel out his promises to us in Jesus!
Grace is the key to joy. The two words go together and have the same root in Greek (grace = charis; joy = chara). Our joy comes from the fact that God has made us right with himself through the work of Jesus Christ, which is given to us as a free gift (grace).
