“There will be those who will say to you, ‘Look, there he is’, or ‘Look, here he is’. Do not go off, do not run in pursuit.”
Personally, in this verse I see a message that cautions us against any practice, devotion, trend, personality, or fad that might draw me away from prioritizing Mass, Eucharist, Reconciliation, prayer, and the practice of virtue. What Christ modeled for us, what he did for us, was perfect and is perfect. There’s no improvement to perfection. No ‘new’ way or better way to achieve it. Prioritization of the basic elements of faith is crucial to a successful relationship with God and spiritual journey.
