In a talk entitled "You Know Enough," Elder Neil L. Andersen said, "Fear and faith cannot coexist in our hearts at the same time."
I know what he said is true, but that doesn't make it less difficult to push out the fears and have complete faith, especially when everything looks so uncertain or unfamiliar...or scary. However, I know there have been times in my life (my mission, getting married, having kids, etc.) where there were plenty of fears that could have overcome me, but my faith was so much stronger.
Maybe I just need to do things to gain a little more faith. :)
I often think about the apostle Peter, who once walked on water because he trusted Christ so much, but then began to sink because he let fear enter his heart. What made him stop believing? What was it that caused him to doubt the Savior, who was right in front of him? Perhaps it was a lesson to him, an opportunity to reach his hand out to the Savior and cry for help to save his life, which maybe we all need at some point. But wouldn't it be wonderful if we could all have as much faith as Peter started out with?
What do you do to keep your fears out of your heart so there is room for faith?
