Socrates said it. Stephen Tong promoted it, mocking those who think they could live through life without mistakes by doing nothing. I do prefer CL Franklin's quote better. I do not remember exactly which sermon he said it in, but I heard it from his sermon series on Youtube while I was in Detroit. DL Franklin is a famous black pastor, famously known for his million dollar voice, as well as being the father of Aretha Franklin in Detroit.
To paraphrase Franklin: You cannot live a victorious life for Christ by doing nothing!
Many pride themselves of the comfort for staying out of trouble, running from facing possible challenges. They think they lived their lives by doing nothing. They forgot, that as Christians, we are also to live a victorious life. You cannot live a victorious life by doing nothing.
Great quote from my SPG weekly from Helen Keller: Life is [either] a daring adventure or it is nothing at all [nothing]. Security does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than exposure.
