If you came because you are afraid that God might punish you, you are motivated by guilt. If you came simply because it is Sunday morning, guilt is your bottom line. His undeserved, unmerited blessings in our lives. Our motivation for being here should be grace. We should be here because we are so overwhelmed by God's love for us that we want to be in His presence, with His people, offering worship in His name, being led by His Spirit and hearing His Word for us.
Pastors are often experts at guilt-motivation.
Congregations are often easily manipulated by guilt. Many times preaching is intended to push our guilt button. Guilt has a purpose in our lives. Guilt should be like the warning light on your car's dashboard. When you feel guilty in your service to the Lord, it should warn you that you are growing cold in your intimacy with Jesus.
