i did a quick search from Genesis to Revelation and one thing was very constant, whether in Captivity, Free, or in Israel established as a Nation, Followers of God, were privy to SEE God do great things. From personal Miracles, to miracles so big 5,000+ witnessed it.
That tells me, a True Follower of God, should be seeing and Witnessing Miracles.
if they are not seeing and witnessing them, the examples seem conclusive, that you aren't part of God if you aren't seeing them.
