Faith. It is a word that we use so often in our day-to-day Christian conversations, but what does it truly mean to have faith? What is the difference between mental assent and true faith in Jesus? How do we detect when we are living out of self-sufficient effort rather than relying on kingdom faith? The struggle for faith to accomplish God’s purposes is what we see playing out in Mark 9:14-29, and as we reflect on this account the Holy Spirit invites us to see ourselves in the story. The event that took place in a village somewhere in the Judean countryside two thousand years ago becomes a mirror that reflects the reality of the faith struggle in our own lives today.
