Good = Good and Evil = Evil

"Woe to those who call evil good and good evil, who put darkness for light and light for darkness, who put bitter for sweet and sweet for bitter." Isaiah 5:20
When riding a horse you yell "WOE" when you want the horse to stop abruptly. Ususally there is an issue ahead or you don't want to fall off the next cliff. Well when "Woe" is stated in the Bible it means, don't do it; or Warning! You are heading in the wrong direction. Even Jesus uses "Woe" when he is talking to the Pharisees, calling them hypocrites and blind guides. They are doing wrong, and Jesus wants them to stop.
Well when Isaiah is writing to the Jews he is saying, 'stop saying something evil is good or something good is evil'. Evil is evil and good is good! Have you ever tried to justify doing something wrong by saying, well it wasn't that bad or I had to lie, it was for their own good. No, doing something wrong isn't for anyone's good. In business, many Christians hurt people in the way to the top and think well it's okay because when I got to the top I was going to do good. No, hurting people on the way up makes nothing good. Good is good and evil is evil! We can't make something bad be good, and we shouldn't sin for a good reason; there is no reason good enough. It is better to be faithful. If we do right things for the right reasons God will bless what we do.
Recently, I was reading the book, The Hiding Place, a story on Corrie Ten Boom and how she made it through the Nazi invasion in Holland, hiding Jews in her home, and being sent to a concentration camp. It was all by her obedience and trust in God. She did things that put her and others at the risk of death, but she was faithful to what God's Will is. One day, she was having lunch with her sister and her niece and nephew. Her nephew, however, was at the age to be taken away to work camps, he couldn't be caught in the streets or he would be gone. While they were at her house a member of the Gustapo came to Corrie's home, and Corrie's nephew hid in a false floor under the table. The Gustapo asked if their was a boy in the house, and Corrie's niece who was taught that God said never lie openly told the man her brother was under the table. The man immediately threw off the table cloth and no boy was to be found. He got angry and left the house. Corrie was astonished, she couldn't believe her niece ratted out her brother, but the niece trusted that God would take care of her family because of her obedience to His Word. I don't know about you, but I'm pretty positive I would have lied. Even though I would have lied for the life of my brother it would have been wrong.
Even when we say a small lie like, "Oh did you get a new cut? Your hair looks great!" and then in the back of our head we are thinking, 'oh honey you shouldn't have done that', it is wrong. Our false information will cause reprecussions.
God says when we sin He will still love us, but their will be consequences to us or others. You never know, if the niece had said a lie, she might have seem more terrified and the gustapo would have searched the whole house and found the others. Or when you tell someone you really like their haircut and there are other mean people out there who may snicker and make comments to her, and her feelings get beaten down  to nothing.
We can't make evil good and we can't make good evil. We just need to keep the good things good, and be obedient out of our love for Jesus. He will provide for us in our Faithfulness.
