Support as the leader of the church. Obey your spiritual leaders, and do what they say. Their work is to watch over your souls, and they are accountable to God. Give them reason to do this with joy and not with sorrow. That would certainly not be for your benefit. Hebrews 13:17
No talking behind the back. Churches, admittedly, because it’s an organization comprised of everyday people, have problems in this area. Gossip keeps the fire going, not talking too much, puts out the fire. Don’t talk about the pastor negatively. Travel down other roads – pray for the pastor, talk with the pastor, build the pastor up when you are talking to others. At the very least, don’t say anything at all! (Proverbs 26:20)
Prayer on behalf of the congregation. The congregation needs to pray for the pastor on a regular basis [4 Things to Pray For Your Pastor].
Encouragement. The pastor needs encouragement. (Heb 10:24-26)
Honest Compensation. As much as possible, the pastor needs to be free from worry financially. This is in part based on the pastor’s desire and diligence to live within his means, but it also means fairly compensating for the work. (1 Timothy 5:18)
Loving Feedback and Christian Accountability. The pastor needs someone to help sharpen the iron – loving and honest feedback on the way meetings are handled, sermons are preached and people are cared for. Any wise pastor will graciously accept this kind of response from people who are for him and even from those aren’t. (Proverbs 27:17, 1 Thes 5:12)
