Is unforgiveness secretly blocking your prayers? In this message from Mark 11:22–25, we look beyond “Do I have enough faith?” and ask a deeper question: “Am I holding on to offenses?” Drawing from Jesus’ words on prayer and forgiveness, the parable of the unforgiving servant in Matthew 18, and the Lord’s Prayer in Matthew 6, we see how clinging to bitterness can turn our prayer life into “airplane mode” before God. True grace not only cancels our unpayable debt of sin, it produces a heart that forgives others from the heart. If your prayers feel like they’re hitting a brass ceiling, this sermon will help you examine your heart, let go of offenses, and seek the kind of forgiveness that leads to unhindered fellowship with God.
