Overseeing Christ’s Church (1 Timothy 3:1-7)

The leaders of the church should desire to rule their lives and the church by the Lord’s standard.  If the Lord’s standard is perfection then how can we be qualified to lead if we are struggling sinners?  If Timothy is serving a church that has struggles then how can Timothy ordain leaders?  What qualifications should he look for in a leader?  How do we know if we should aspire to hold leadership in a church?
