Behold, the man is become as one of us, to know good and evil. Genesis 3:22

The ways in which we learn are through information, experience, and observation. Experience is by far the most effective method. For six thousand years God has been teaching the world the exceedingly bitter results of sin, by permitting evil to prosper. In the kingdom, when righteousness is the rule, the contrast between the consequences of good, and evil, will be very clear to all, so people can make a proper choice. Genesis 3:5
