The Bible reveals God, it doesn’t contain Him. He is free to act outside of what is recorded in scripture. The Bible reveals His ways. The question we should ask, do unusual signs violate the way He deals with people? Secondly what was happening when these signs appeared? Thirdly, where do the signs point? Ours happen mostly during worship or the preaching of God’s word. Signs are to restore the wonder.
Some people are like a black hole, they drain all light and life that comes near them and they are no better for it.
John Paul Jackson
