This post very clearly is not on the right path, calling out an interpretation error and then attempting to provide what the correct interpretation should be is simply not okay. Truly, I am thankful not to be in the shoes of whomever is writing these answers because you are on unsteady ground. We all will be judged in the end. People, be wise and read the Bible for yourself, ask trusted friends or believers that you hold in respect to help you with interpretation if you don't understand. Do not go to GotQuestions.org, in my opinion, they are a stumbling block to others.
