When you get right down to it, most of what Jesus preaches is HOPE. He is the ultimate optimist, for he knows that everything truly will turn out okay in the end. He knows that his love is greater and far better than anything. He knows that his grace covers everything. And he requires SO LITTLE. Only that we believe him. Believe his words. Believe his miracles (this passage is full of them!). Believe his constancy. Believe.
Stop. Breathe in that word. Close your eyes. Do not be afraid. Believe. Like a child. Like a new follower. Believe. Soak it in. Let it fill you. Let it ease away the fears and pain.
