Pastor Shane Kelley's sermon "Callous OR Contrite" focuses on the distinction between having a calloused spirit and a contrite spirit. He explains that calluses in the spiritual realm can hinder our ability to be receptive to the Holy Spirit. The sermon emphasizes the need to clear away obstacles in our hearts and maintain a humble and repentant attitude. Through personal anecdotes and biblical passages, Pastor Shane encourages the congregation to prepare their hearts for God and experience restoration and healing.
