The elders as their main duties are to lead the church by example, teach the Word, and help edify and encourage the body to grow individually and together. Peter charges elders in 1 Peter 5 to "shepherd the flock of God among you, exercising oversight not under compulsion, but voluntarily, according to the will of God, and not for sordid gain, but with eagerness, not yet as lording it over those allotted to your charge, but proving to be examples to the flock." Among our elders is our pastor/teacher, one who the Apostle Paul tells us should excel at preaching and teaching.
God's bar is high for elders. Paul instructs the elders in 1 Timothy 3 as follows: "An overseer, then, must be above reproach, the husband of one wife, temperate, prudent, respectful, hospitable, able to teach, not addicted to wine or pugnacious, but gentle, uncontentious, free from the love of money. He must be one who manages his own household well, keeping his children under control with all dignity... and he must have a good reputation with those outside the church."
