When we have faith we have the experience of complete, total inner peace and contentment. We feel very centered in the present because we know the future is going to be fine, no matter what. With faith we are not attached to a future outcome. With attachment there is always fear and the feeling that we won't be okay unless things work out in a particular way. Faith is also not the same thing as wishing.
Faith produces results.
Wishing keeps us focused on what we don't have. We feel lack rather than peace. Seek out people who have more faith than you or at least support your faith. Find a friend, a group or a spiritual teacher whose faith will spark your own. Read books about Mother Theresa, Peace Pilgrim or other stories of faith in action.
