Paul wrote to his friend Titus about appointing elders for the churches they had planted. Titus 1.6-9 lists the qualities to look for:

• Above reproach
• Husband of one wife
• Children are believers
• Children are not open to charge of debauchery
• Children are not open to charge of insubordination
• Not be arrogant
• Not be quick-tempered
• Not be a drunkard
• Not be violent
• Not be greedy for gain
• Be hospitable
• Be a lover of good
• Be self-controlled
• Be upright
• Be holy
• Be disciplined
• Hold firm to the trustworthy word as taught
• Be able to give instruction in sound doctrine
• Be able to rebuke those who contradict sound doctrine

This is a lonnnggg list.  Prospective good elders will invariably say they cannot possible meet the standards; the bar is too high.  It is only by the grace of God that we can try and sometimes succeed.
