Verses that talk of stricter judgement / accountability on church leaders

How are Christian leaders supposed to deal with verses that talk of God's increased judgement on church leaders? Such as: > James 3:1 "We who teach will be judged more strictly" > Hebrews 13:17 "Your leaders... must give an account" How can people step into church leadership and willingly put such a 'sword of Damocles' over themselves? In fact, I see most people in churches do exactly the opposite. When asked to take a responsibility or a leadership role, they run away fast. And who can blame them if God has promised to smite them if they lead, but then inevitably make mistakes? Put another way, what bible verses can encourage those who are afraid of the consequences of the above two verses, yet still feel called to some form of leadership?
