He also mentions the difficulty to live with UBF Korean parents who are UBF missionaries. You will see that UBF Korean missionaries apply their Korean-style parenting to "discipling" their sheep and UBF-style discipling to their parenting. One will conclude after reading the life testimony that the whole UBF paradigm of serving God's work should be dismantled since it is only based on Korean culture but never on the Bible.
Nobody seems to understand this poor 2nd gen. His parents are just trying to mold their son into a loyal UBF member. And everyone in UBF is collaborating to achieve this goal. I think that they are trying to suffocate him. They must teach him the truth and freedom in the Gosepel of Jesus. Otherwise, they will only make his heart hard toward God. They might succeed in making him a loyal UBF member. But they will never succeed in making him a true child of God. I think that his parents have more problem than he does. The best way to solve the problem is to for the parent to leave UBF with their son. I did and it is working.
