Life of a child of God is a life that presents uncertainty in a positive light. It will be a lie to say it is easy, it is not easy, and even God did not promise that it will be easy, but what we experience when its not easy is the hallmark. He promised in Isaiah 43:2 that When you walk through the fire of oppression, you will not be burned up; the flames will not consume you.
What can make you believe this even while in the fiery furnace if not FAITH, the confident assurance that something we want is going to happen. It is the certainty that what we hope for is waiting for us, even though we cannot see it up ahead. Hebrews 11:1TLBV
Almost every Christian knows this passage, we know how important it is to our growth as children of God, God will never take it for granted in our relationship with Him and in the fulfilment of our purpose, because without faith it is impossible to please God,… as you come to Him, you must believe that He exists and that He is a rewarder of those who diligently seek him. Hebrews 11:6-7
