“If the world hates you, keep in mind that it hated me first. John 15:18 NIV
Can you walk in the rain without your shoes getting wet? Of course not. It is equally impossible to express boundaries without someone getting mad about it. As Christians, we can be overly worried about making others mad. Of course we are never to provoke others through misconduct. We live in an age where people are offended by the slightest thing so we may be tempted to be silent just to keep the peace.
Jesus never focused on people’s responses to the truth. He determined to do the Father’s will. The response His listeners gave was their business. He knew that God had given every person a free will. He let them exercise it however they chose, but He never changed His message. You and I must have the same focus.
Boundaries are a form of expressing the truth. Boundaries are a gift from God. If you allow others to break those boundaries through intimidation, you suffer for it. I know it is uncomfortable when people respond with anger when you say what they don’t want to hear. Know that it is the truth they are responding to, not you. Pray God softens their heart and opens their eyes, my friend. This is a spiritual fight, and you have already won when you speak the truth.
