You will run into problems, situations, and people that will make you feel unaccepted. You will step into venues where you are not the favorite. You will be around people who do not believe what you believe. None of these are good enough reasons to stop. You have a friend in Jesus who went through this exact situation in the sixth chapter of the book of Mark.
He was not accepted by His own kind. He was not believed. He was rejected and belittled. Even so, the Bible lets us know that He still did what He was supposed to do. These were not acts that He discerned or that were being done behind His back. These were direct in His face rejections by people who should have understood Him the most. You are not alone in this struggle. You have the power in you to push forward and keep working.
