We didn't understand until it had been and gone. We have to take time to think how we can make God happy to the bottom of His heart and how we can make True Parents stop worrying. Some members tried many things for that end, applying the Principle in their own way. Sometimes they made mistakes. Father teaches us what we need.
Members are different in their growth.
For example, some have the same spiritual standard as those before the Old Testament, others as those in the Old Testament and others the same as the New Testament people. It is difficult, or rather impossible, to teach them in the same way. Father gave members personal advice as well as general teaching. Normal hours were more important than the time of the Sunday service. At the Sunday service he taught, for example, what God's heart was, a very basic thing, or how Jesus was lonely and sorrowful when people didn't listen to him even when he came with God's words.
