Faith is very important since all that was done in the Bible was done through faith. You must have a personal relationship with God, you must know Him and have the demeanor to follow him to the end. Having faith is accepting the plans of God even though we do not understand them. It is getting up when you have fallen, it is trusting, but not only in things but also people. Having faith is choosing God over all things, remember that He is always walking at your side, allow Him to enter your heart and you will see He has always been with you.
