From Psalm 118, 8-9:
Better to take refuge in the Lord trust in mortals. Better to take refuge in the Lord than to put one's trust in princes.
How many times do we get angry at someone else throughout any given day? For inane reasons, jealousy, fear, impatience, righteousness, malice, vengeance and despair? We look to our friends and family, coworkers and lovers, but all these people can provide no perfect answer. Their hearts cannot love like God's. Their mind cannot think like God's. At best, we discern through the Spirit what God wants of and from us every day and at worst we let our selfish tendencies form our motivations.
When we get angry, or frustrated, or for whatever reason, why do we look to anyone but God? It's unfair to us, and them, when we expect solace, or guidance, or even a secret-keeper. Those mortals close to us are human - faulty and broken. God is the only one we can turn to in comfort, reason and full faith.
Turn to God in the sacraments, in prayer, in community and in evangelization. Live your life with and for God and you will find joy!
