“If you had known personally, even at least in this your day, the things that make for peace (for freedom from all the distresses that are experienced as the result of sin and upon which your peace–your security, safety, prosperity, and happiness–depends)! But now they are hidden from your eyes.
“For a time is coming upon you when your enemies will throw up a bank about you and surround you and shut you in on every side. And they will dash you down to the ground… [all] because you did not come progressively to recognize and know and understand [from observation and experience] the time of your visitation [that is, when God was visiting you, the time in which God showed Himself gracious toward you and offered you salvation through Christ].
“For it is written, ‘My house shall be a house of prayer; but you have made it a cave of robbers.'”
