"First of all, then, I urge that supplications, prayers, intercessions, and thanksgiving be made for everyone, for kings and all who are in high positions, so that we may lead a quiet and peaceable life in all godliness and dignity" (1 Timothy 2:1-2).
The two letters addressed by Paul to Timothy are instructions concerning the fledgling church in Ephesus. Others have been imposing various rules and regulations that Paul sees as antithetical to the true purpose of Christianity. In the first chapter he defines that purpose as "love that comes from a pure heart, a good conscience, and sincere faith" (1:5). In the second chapter he gets more specific. There should be no discrimination about who does or does not deserve the prayer support of the church. They should pray for all people equally no matter how important they may or may not be. It's only by extending blessings to all persons equally that "a quiet and peaceable life" becomes possible.
