The Holy Spirit is my sensor because he lets me know right away when my thought or feeling is inappropriate, showing lack of love. For example, yesterday someone phoned me and I knew that talking to that person would be unpleasant ~ the Holy Spirit calmed me down and I was able to listen and talk nicely. Again, this morning at church before Mass started, quite a few of us were praying, but two people in the back started talking in a low voice, making it impossible to concentrate on praying. The Holy Spirit again calmed me down and the talking stopped after several minutes. So the Holy Spirit senses my reaction, checks me, and renews me. Let the Lord renew us every single moment that we may remain new at all times.
