We're like the father who had the demon possessed son. He told Jesus that if He could do anything to please help his son. Jesus then responded "If you can? All things are possible to him who believes". The father then responded, "I believe, but help me in my unbelief."
That's where many of us are in this walk of faith we're taking. Intellectually, we believe what the Bible and what Jesus said. But, in our hearts, down where it really matters, we struggle with unbelief. Some of us struggle mightily with unbelief.
Why do you struggle so much? Why do I struggle so much? We want so much to believe, yet we find it so hard to believe at the same time. You look around and see the way things are in the world or perhaps even your own life, and those things you see, really cause you to struggle.
But there's great news. Faith doesn't have to be that kind of a struggle. Keep in mind, I didn't say faith would come easy or that we'll have the kind of faith we need all the time in every single situation. But, faith doesn't have to be the struggle you and I often think it is.
