Christians are called to be leaders. If for no other reason, we are to “lead” people to Christ through the examples we live out. A spouse, manager, or any other in position of authority is classified as a leader. All leaders in any capacity are expected to reflect godliness in their leadership positions.
The Bible reference
“Therefore I exhort first of all that supplications, prayers, intercessions, and giving of thanks be made for all men, for kings and all who are in authority, that we may lead a quiet and peaceable life in all godliness and reverence. For this is good and acceptable in the sight of God our Savior”
(1 Timothy 2:1-3). (Acts 20:28 KJV)
