'Restrained' in the Bible

But now we have been released from the Law and its penalty, having died [through Christ] to that by which we were held captive, so that we serve [God] in the newness of the Spirit and not in the oldness of the letter [of the Law].

For the mystery of lawlessness [rebellion against divine authority and the coming reign of lawlessness] is already at work; [but it is restrained] only until he who now restrains it is taken out of the way.

Then I fell down at his feet to worship him, but he [stopped me and] said to me, “You must not do that; I am a fellow servant with you and your brothers and sisters who have and hold the testimony of Jesus. Worship God [alone]. For the testimony of Jesus is the spirit of prophecy [His life and teaching are the heart of prophecy].”
