If you do have a legitimate beef, then talk directly to the pastor and avoid spreading the seeds of your discontent among other members. They can't help the situation, and your criticism will only breed a spirit of negativism in the church. The same goes for criticizing the pastor in the presence of his or her spouse. Pray for and with the pastor. Instead of criticizing the pastor, pray for and with him or her.
Pastors are special targets of the enemy.
Discouragement is Satan's number one weapon against God's spiritual leaders. We can support our pastors by praying specifically for God to protect and bless them in several key areas. Ask God to give your pastor a servant's heart and a teachable spirit. Pray that your pastor will be sensitive to God's leading, able to discern His plans and purposes. Ask God to place a hedge of protection around your pastor, keeping him or her in good health and safety when traveling.
