Hebrews 13:17 (ESV)

17 Obey your leaders and submit to them, for they are keeping watch over your souls, as those who will have to give an account. Let them do this with joy and not with groaning, for that would be of no advantage to you.

To preach this text in your situation you must identify what culture you are part of. The cultures in this world have a different approach to authority. There are egalitarian and authoritarian cultures. When you live in an egalitarian culture, it is wise to emphasize the authority of the leaders in the church. They have authority when they speak the Word of God. But when you live in an authoritarian culture, it is important to stress that the authority is not the authority of man but only of the Word of God. You can also emphasize that a man with authority cannot do what he likes because he has to give account to God.
