Too many off of separate our lives into 'spiritual stuff' -- those things where we seek God's will -- and 'personal stuff' -- which is everything else. But Jesus tells us that we are to love God with our whole selves -- our thoughts and reactions, our reason and judgment, and yes, even our dreams. Dreams are like dynamite, with the power to demolish strongholds or to destroy us or those around us.
All our dreams should be from God. He uses dreams to destroy the nightmares of this world.
