Committed leaders are the ones that eliminate those activities in their lives that keep them from fully responding to God's call. This includes having time for God and prayer in their schedules and time with their spouses and families. This also includes having the time to provide for their families either at work or in the home and the time to receive training and growth as a leader. Serving in a leadership role also requires having the time to meet with pastoral or core team members on nights other than the regular prayer meetings. Committed leaders that can strive to do all the above things are the ones that are driven with a burning desire to carry out God's vision for their communities.
Humble leaders are servants who wash the feet of others.
They humbly acknowledge their own weaknesses and realize they aren't expected to be perfect. They also allow others the room to grow and make mistakes. True leaders have the ability to gently and lovingly challenge others to grow in the use of their charisms. They are obedient to church authority, especially their pastors, even if they disagree with them. Finally, true leaders have learned how to put balance in their lives.
