Bible says that we should live by faith. Without God, “we live by sight” but with God, we “live by faith”. Having faith in the Almighty does help to keep our minds at rest and ease. We know there is someone who will take care of us. It is like a driving force that helps us to fight the battles of life.
Having Faith does not mean that things will turn our way the moment we fold our hands and pray. It means we have him with us, no matter what and he will not let us fall. He has his own timings and Things will be favorable only when he will wish them to be.
Until then, the faith in Him will help us to survive, fight and win.
