The third rule John Wesley, founder of the Methodist movement, calls 'Attending upon the Ordinances of God'. I can understand why the author, Bishop Job, of the Three Simple Rules, changed it from Attending… to simply: staying in love with God. BUT I also think that 'staying in love' with God makes it sound too easy. It's really not enough to SAY 'I am a Christian' and it's way more than just saying 'I love God!'  https://horizons.church/events/3-simple-rules/
