Fear comes when we have inadequate resources. My third bit of advice concerns the only known cure for fear. It is faith. Some people argue that faith is the opposite of fear. I m not so sure about that, but I do not that faith is the cure, the only cure, for fear.
Faith is a synonym for trust.
If we trust that God will take care of us, we should then have no fear. First, make sure you live right so that you do not have to fear God. Second, make sure you have adequate resources. You are never alone when you know Christ. Drive your stakes into the solid rock.
