“There is always a fundamental seriousness about the men and women who are born again. I mean something like this: they are never flippant, never light, never superficial... they are fundamentally serious people.
"Let me hasten to add that I am not saying that they are solemn or pompous people. God forbid that anyone would think I am saying that! No, no, they are happy, they can even be humorous. But their humor never runs away with them. It is a manifestation of life; it is the showing of one of the attributes that they have received by nature...
"We have suggested that when someone is born again, that is the most obvious thing about him; it must be, for it is the life of God in him. He is also conscious of being dealt with, of having been humbled; he is also aware of a true repentance, and he is characterized by a fundamental seriousness.”
