Many Korean companies force their employees to sacrifice their family life in roder to increase corporate productivity. Likewise Samuel Lee forced UBF members to sacrifice their family life to expand UBF business. Some UBF members had to leave their children home alone to attend many UBF meetings to increase UBF productivity. UBF leaders still condemn any desire to have a good family life as sin of family-centeredness.
If anyone asks the UBF leaders what is sin of family-centeredness, they won't give any good biblical answer. If one doesn't attend a UBF meeting to spend a quality time with his/her baby, then it is sin of family-centeredness.
