There used to be a cute saying: “God couldn’t be everywhere, so He made mothers.” The theology might be better expressed as “God is everywhere, but He works through mothers (and fathers).”
What we refer to as “relational disciple making” is not a program.
There are books about it, just like there are books about parenting– but you don’t become a parent by reading books.
There are materials that might aid you in doing it, just like there are things you might find helpful as a parent–but you aren’t a good parent because you have the right materials.
The core idea is that someone who is immature in their faith, like someone who is immature physically, needs protection and help from someone who has “been there and done that,” and maybe has the scars to prove it.
It is simply one believer saying to another “I will help you if you would like me to…” and another believer saying “maybe I do need some help.”
No program will do that. No program really can. There is no one “right way” to do it.
But, like a loving parent, there is no substitute for it.
God makes disciples, but He works through disciples to make disciples.
Paul describes it in 1 Thessalonians 2:5-8
For we never came with words of flattery, as you know, nor with a pretext for greed—God is witness. Nor did we seek glory from people, whether from you or from others, though we could have made demands as apostles of Christ. But we were gentle among you, like a nursing mother taking care of her own children. So, being affectionately desirous of you, we were ready to share with you not only the gospel of God but also our own selves, because you had become very dear to us.
