As a growing disciple, I was trained in various ways through message delivery, drama performances, testimony sharing and serving CBF. I also received a great deal of training from Little Sarah ... I will always be indebted to her for her labor of love.
That's where they want people to have, that's what UBF leaders would call a success story and what they want to be written in testimonies for others to imitate.
I believe that 1) it is totally wrong of Christians to "train" with personal trainers in the sense of UBF, and 2) that it is totally wrong to make others become "indebted" or somehow loyal to you.
"So neither he who plants nor he who waters is anything, but only God, who makes things grow."
"Freely you have received, freely give."
Not everyone should be a teacher. And even if you are a teacher, you can only plant and water, not "train". And even if you can plant or water, you cannot be proud of that or expect others to "pay something back" to you (money, time, loyalty and obedience, as demanded in UBF).
