Jared Moore has a good post here on 5 common things pastors do with unbiblical implications. The post is based on the premise that everything we believe or practice reveals God’s glory or hides it:

1. When preaching for emphasis, we’ll make this observation, “Do you see where God repeated Himself? It must be important then.”
2. When we pray before we preach, or we pray for someone else that is about to speak, we will pray for an anointing.
3. When we honor mothers, fathers, soldiers, or our nation during our worship services, we mingle the worship/honoring of our God with the honoring of graven images.
4. When we refuse to practice or encourage our churches to practice biblical discipline, we communicate that God’s discipline toward those whom He loves is not really love.
5. When we preach/teach only positive sermons, we communicate that God is incapable of moving through His unadulterated Word.
