'Observation' in the Bible

It seemed good to me, having made observation, with great care, of the direction of events in their order, to put the facts in writing for you, most noble Theophilus;

And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:

and they will level you to the ground, you [Jerusalem] and your children within you. They will not leave in you one stone on another, all because you did not [come progressively to] recognize [from observation and personal experience] the time of your visitation [when God was gracious toward you and offered you salvation].”
