Read John 16 today.

John 16:1-4 NLT[1] “I have told you these things so that you won’t abandon your faith. [2] For you will be expelled from the synagogues, and the time is coming when those who kill you will think they are doing a holy service for God. [3] This is because they have never known the Father or me. [4] Yes, I’m telling you these things now, so that when they happen, you will remember my warning. I didn’t tell you earlier because I was going to be with you for a while longer.
I think this is one of those passages I need to keep in mind whenever I am feeling the need to condemn someone else with my thoughts, words or actions. Sometimes we do this without thinking about it. At other times we think about it, but we believe we are doing it as a favor to God or as faithful instruments of God. Convicting others of their sin and their sinfulness is the job of the Holy Spirit. Mine is to share the Good News of Jesus Christ.
