Confronting your fears and doubts protects your faith from being compromised. You can’t confront what you refuse to acknowledge even exists. It’s reasonable to have some level of doubt related to your involvement with God, especially given the fact we are all finite beings attempting to have a relationship with an infinite being. Denying your doubt only empowers it to eat away at your faith, like termites eat away at the structure of a house until it begins to collapse. When you confront your doubt, you acknowledge its existence and therefore have the capacity to limit its impact on your efforts to trust God.
Jesus said to him, “If you can believe, all things are possible to him who believes.” Immediately the father of the child cried out and said with tears, “Lord, I believe; help my unbelief!” -Mark 9:23-24, NKJV
