Why trust God

We are not called to "trust" God to give us everything we want in this life. What we can trust God in is to give us what we need to overcome sin and attain eternal salvation. That is at the heart of Divine Revelation and Christianity itself. We can trust that He is willing to give us everything that would lead us to that end. All the other things, including our physical health and life itself, are not ours to expect or demand anything from God. 

It's like saying a child should be able to "trust" their parents never to allow doctors to give them a shot. But the child doesn't understand that the shot could save his life. 

Similarly, we should not assume that God would not allow unpleasant or difficult things to happen to us if they can ultimately lead us to eternal life. What we should assume, though, is what St. Paul states in Romans: "We know that all things work for good for those who love God." 

Perhaps souls are able look back from heaven to see how everything that occurred to them earth, pleasant and unpleasant, worked together for the eternal Good they experience now and will experience forever.

Things are not feelings

We have a way of evaluating everything that happens, and every possession we acquire, in terms of what feelings we believe are promised by a given thing or event. The material event and the feelings that event represents are not the same thing. But we forget that all the time.

All we ever seek, and all we ever avoid is our feelings. Feelings run the world. They constitute the only useful product of all material transactions between humans and their environment. Just like your body can’t use the food it eats for energy until it’s turned to glucose, we can’t really make use of the things we seek until they deliver certain feelings. Feelings are the currency of human experience. They are the only real incentive.

If I’m not conscious of what material thing is symbolizing what feeling in my mind, then I run the risk of mistaking the material thing to be what I actually want, or what I want to avoid.

The dysfunctional hoarder you see on television has lost track of what she wants. She’s trying to hoard feelings of safety from the guilt she feels when she wastes things. Her stuff symbolizes that feeling of security to her, and so she sleeps on a patch of futon that she clears magazines from each night.

The terrorist who bombs the synagogue is trying to blow up his feelings of frustration and powerlessness over living in an occupied territory. He believes he’ll find the catharsis he needs by doing this.

The overextended husband who buys too much house thinks he is actually buying relief from the shame he feels about having grown up poor. He won’t get that relief, and he will pay dearly for trying. He thinks the house is what he wants.

All terrible decisions, made ultimately in the pursuit of happiness.
