A.W. Tozer emphasizes the peril of being in a spiritual rut, which he describes as a bondage to rote practices that can blind us to our true condition. He illustrates this with the analogy of a man who is critically ill but unaware of his sickness, going about life as if everything is normal. Tozer warns that this lack of awareness can lead to spiritual danger, as we may not recognize the bondage we are in. The sermon calls for self-examination and awareness of our spiritual health to avoid the risks associated with complacency. Ultimately, Tozer urges listeners to seek a deeper connection with God to break free from the rut.
