Happiness is a Changeling
Human happiness is a fluid reality when it is based on the flittering fairies of cultural expectation and personal desire. But happiness that is based in God survives all things and carries you along when difficulties arise.
Fight the power of evil and all of its degrading, humiliating, disappointing, frustrating, fear-mongering tactics with the power of the nails that drove through the arms and legs of Christ, the splinters of the wood that flayed His back, and the thorns that pierced His head.
The cross is a visible sign of our stability and the source of our current and future joy. As it says in Proverbs 3:18, happiness "is a tree of life to those who lay hold of her".
