The Bible clearly teaches that Christ equips the local church for effective ministry:
And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: Ephesians 4:11-12
If an outside resource is used (Financial Peace University and Reformers Unanimous being excellent examples that I can highly recommend), it must become a part of that church. Cookie cutter ministries won’t last long, because there are no cookie cutter churches! Someone in the church must be responsible for adapting the particular ministry to the local body of believers.
We must have ministries, not merely rent, hire, or test them out.
And if Christ leads your church to adopt a ministry strategy, He has equipped your church with just the person to lead it!
Maybe….it’s you!
What ministries does your church utilize effectively?
