Today in the world, people are free to do what they see fit with their hearts and lifestyle, but in the past, God do sometimes, come down from heaven, and He want to see how wicked men are before sending in a judgement upon them, for example in the days of Lot, God sent two angels who came and see how wicked was Sodom, and in the days of Noah, God came and see for himself, how wicked men were before He sent in judgement, so today, it's true to make a different in your life to make things right with God by repentance of your sins, before it become too late.
