As a teacher, I do at times find myself about to react out of anger towards my students. Sometimes, I still do lose my cool. But more and more, something hits me in the moment, reminding me of God and I realise what's about to come out of my mouth isn't going to be very loving at all.
In that pause, I'm faced with the decision to react or respond. I call it a healthy tension because if I'm aware of such a tension in me, it means God is guiding me and that by grace, I am also allowing myself to be guided by Him.
