Equanimity is one of the fruits of a life that is given to faith, worship, and prayer. We go through our difficulties, small and large, and take our troubles to God. We learn that we must ask not for a specific outcome, but for God's will to be done, for the highest good to be served. In this prayer and faith, we gradually move into the experience of trust: not the kind of trust that something in particular will happen, but a purer form of trust: just trust. Be confident that you live in God, and no matter what happens or doesn't happen, you still live in God and life will still be good. This brings equanimity, the "peace of God which surpasses all understanding," as St. Paul put it (Philippians 4:7).
