Doubts can damage our faith. As christians, we are not exempted to experience the challenges and difficulties in life. And GOD allows us to go through such situations not to break us but to mold us into having a good character. Equip enough to handle and face all the battles in life. GOD tells us that we are not alone in this battle, and HE assures us that HE is in full control. Therefore, we should not worry but trust the LORD more.
