It needs to be acknowledged that the overwhelming majority of the congregation does not feel a call into the ministry. If you are not someone feeling this call, then your responsibility is to continue to do what a faithful church member does. Invest and pour your life into the people of the church so that when the time comes to possibly affirm someone for the ministry, you are well informed.
When a young inexperienced brother is given an opportunity to teach Sunday School or preach on a Sunday evening, take the time to go and attentively listen. Approach them afterwards and encourage them with what you thought they did well and lovingly correct them where they can improve. Put your personal preferences aside about who you like better as a preacher, and embrace the opportunity of someone else being able to grow and learn from his experience. If a young man calls asking if he could come to visit you, love and encourage him as he makes the effort to learn and minister to you.
God has a specific and important role for every member of the church to play to test, train, affirm and send those called into the ministry. Church members, embrace this privilege. Pastors, train your people to think this way.
