Help my unbelief!

“Immediately the boy’s father exclaimed, ‘I do believe; help me overcome my unbelief!’” Mark 9:24
Here is a cry that we all utter at some point in our Christian walk. Something huge is before us, and although we know in our heads that God can do it (because nothing is impossible for Him), we have difficulty believing it in our hearts. But there is comfort for us here.
Jesus spoke about faith, saying, “I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there’ and it will move. Nothing will be impossible for you” (Matt. 17:20). Have you ever seen mustard seeds? They are tiny! We don’t need a lot of faith for God to use it and work through it. And like a seed, faith grows as we use it. It is like a muscle: if we want our physical muscles to be strong, we must put them under some strain, by running or lifting weights. We need to stretch them – and it is the same with our faith. Believe what you can, and leave the rest up to God to work. Start by confessing, “Lord, I know it says in Your Word that You have promised...” You might even admit, “I don’t know how You can fix this situation, but I know that You can do all things.”
This is the first step in building your faith. Overcoming unbelief is similar. Faith says, ‘God can do it.’ Unbelief says, ‘It can’t be done.’ So the first step to overcoming unbelief is to refrain from saying it can’t be done. Instead of focusing on the problem, focus on God who has all the answers to every problem. It won’t happen overnight, but if you keep working at it, it will happen.
