Imagine if every little baby that was born anywhere in the world had an invisible digital recorder hung about his neck. And this tape recorder only recorded the moral judgments which this child made against others. Every time this child starts to say, “You ought,” or “You should,” it starts to record. Eventually this baby grows up and dies and comes to that great moment when he stands before God as judge. Suppose, then, that God simply touched the playback button on the digital recorder and he heard all his words playing through the speaker. All those statements throughout the years said by his voice where even the tonal inflection in his voice was heard clearly. Each and every statement he had made against others in moral judgment. God says, “I’m going to be really fair. I’m not going to judge you by my standards (Ten Commandments, Sermon on the Mount, etc.) but by your standards.” He could hear it going on for years — thousands and thousands of judgments made against others.
Not a single person would pass this test.
