When I discuss TRUST with a group of people, I commonly break down my definition of trust and how it requires a risk and fear. Otherwise it is not really trust. Commonly, the question then comes, "What if you choose to trust and then you are taken advantage of? What then?" The question brings up a decent point, but we can often allow this to really get in the way of our trusting someone. We have, in asking that question, defied our ability to trust. Trust cannot be dependant on its outcome. If your trust (or lack) is based on the proposed outcome, then you have not trusted at all.
Yes, it is possible to risk and trust someone, and it is possible that it will bring hurt in some cases, but IF you make your decision based on a proposed fear or outcome not to 'go', then you have not trusted.
This applies both to our human relationships as well as our relationship with God the Father. If my trust in God is based on whether or not he gives me tangible affirmation, then I have not trusted God at all. If my trust in my Father is whether or not he moves me to FEEL his presence, I do not really trust God.
TRUST BASED ON THE OUTCOME IS NOT REALLY TRUST!
If I spend the majority of my life demanding that God prove himself to me and assure me that he exists and works in my life, then I have not yet learned what it really means to trust God...to have faith.
We all want to be trusted. "Just trust me will ya!" God is no different here. He desires to be trusted. What sort of demands have we put on that trust? We have so many ways in which we demand a certain outcome in order for us to trust in God, but that is no trust in God at all. We have to learn how to trust God even when the outcome is uncertain...otherwise, we will not have trusted at all.
