The Bible says in Ezekiel 14:12-20, "The word of the LORD came again to me, saying, Son of man, when the land sinneth against me by trespassing grievously, then will I stretch out mine hand upon it, and will break the staff of the bread thereof, and will send famine upon it, and will cut off man and beast from it: Though these three men, Noah, Daniel, and Job, were in it, they should deliver but their own souls by their righteousness, saith the Lord GOD. If I cause noisome beasts to pass through the land, and they spoil it, so that it be desolate, that no man may pass through because of the beasts: Though these three men were in it, as I live, saith the Lord GOD, they shall deliver neither sons nor daughters; they only shall be delivered, but the land shall be desolate. Or if I bring a sword upon that land, and say, Sword, go through the land; so that I cut off man and beast from it: Though these three men were in it, as I live, saith the Lord GOD, they shall deliver neither sons nor daughters, but they only shall be delivered themselves. Or if I send a pestilence into that land, and pour out my fury upon it in blood, to cut off from it man and beast: Though Noah, Daniel, and Job, were in it, as I live, saith the Lord GOD, they shall deliver neither son nor daughter; they shall but deliver their own souls by their righteousness."
In the above verses of scripture God was speaking to Ezekiel about judgment upon Israel. In essence, God was saying that men such as Noah, Daniel, and Job could not offer enough sacrifice, (See Job 1:4-5) to even save their own children from judgment. That is a scary thought. Yet it is in full agreement with the New Testament in Romans 14:4 that says, "Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand." The day will come that will be the final moments of time before the Lord Jesus returns. How important then is it to do what the Lord said in Mark 13:34-37, "For the Son of man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch. Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning: Lest coming suddenly he find you sleeping. And what I say unto you I say unto all, Watch."
