In this passage John challenges us to “abide in Him” in order that we be prepared for the Day of Judgment. Persevering all the way to the end can seem overwhelming! We consider the practical approach of Dr. William Osler, a famous Christian physician who advocated living life in separate day-by-day compartments. We also examine John’s challenge to “practice righteousness” in light of the popular claim (based on Romans 3) that “no one is righteous”. Finally, John tells us the reason Jesus came was “to destroy the works of the devil”, a concept foundational to having a full picture of the gospel message.
