According to the process, men are born again. They are baptized and filled with the Holy Ghost. They fellowship and edify one another. They are discipled and spend time in worship. Then, when God speaks, they are sent away to do a work. That's it! There is no need to dress up, develop a program and invite a speaker. No one cares if the appropriate bishop or apostle is in the room. It's out of an atmosphere of unified prayer and worship that miracles and ministry calls come forth.
Notice that even Paul and Barnabus were not required to complete a course or serve any particular length of time "in training" or "in service" before they were sent. With all our biblical examples, we see many instances of those who are sent and appointed. The key is not what they've accomplished in the natural, but the call God has placed upon them. Notice that in the word of God there are no ministry interviews, qualification exams or annual convocations for which people were required to "wait" before obeying God.
I'm convinced that the church is losing out on the ability to reach more souls, at least partially due to our tendency to feel that those called must be justified by us, as if God's call is not sufficient. Let's be honest... how many of us were "ready" (in the eyes of our peers) when God called us? While we must live lives of holiness, sanctification and obedience to God, we all make mistakes, and it's okay. By the grace of God, we learn from them. Look at the lives of Peter, Paul, Timothy and others. They all made mistakes, and they LEARNED WHILE WORKING. They remained accountable and received both rebuke and encouragement from one another WHILE WORKING. The greatest teacher is not one's pastor or apostle, but the Holy Ghost. So, why should we rob others of the best lessons they could possibly learn. When God instructs us to send, it out NOT our job nor responsibility to qualify that call. It's our responsibility to obey, pray for and support them in the work.
Yes, discipleship should continue. Training should continue. Maturity should continue. Yet the work must go forth. We've got to trust the process. Trust God and simply obey Him when He speaks. Loose them, and let them go! After all, God's people are just that... GOD'S people, not ours. Selah.
