Sometimes we think we have faith, but what we believed for, didn't happen. We wonder why not: was it a lack of faith, why did God not come through, maybe it was the devil? But it could be we presumed God to do something, or we are trying to make Him to do something, thinking that is His responsibility, when in fact it is our responsibility.
Some real life examples and what we can learn from them.
