Joy is always a function of gratitude - and gratitude is always a function of perspective.
Lament is a cry of belief in a good God, a God who has His ear to our hearts, a God who transfigures the ugly into beauty. Complaint is the bitter howl of unbelief in any benevolent God in this moment, a distrust in the love-beat of the Father's heart.
When grief is deepest, words are fewest.
Being joyful isn't what makes you grateful. Being grateful is what makes you joyful.
All fear is but the notion that God's love ends.
You can give up the need to compete in the world- when you accept being complete in Christ.
