Faith is fervently believing in things that is impossible to happen. Like we always hear, faith can move mountains. Now why mountains? Mountains symbolize things that are usually difficult to accomplish or too impossible to happen. So thinking about the impossible, some people either lose hope and be sorry for the rest of their life.
When difficult times arises, what we need to accomplish the impossible is LOVE. When you love what you do and doing it for others out of love, it becomes your strength and inspiration. You will be more concerned of making others happy and cheering them up is a way to cheer yourself up.
The more you believe and act on it, the more possible results you get. And the main ingredient for that is you gotta have love.
