As the Church is the ‘pillar and support of the truth,’ what it teaches matters. Dr. John opens 1 Timothy 4:1-5 to alert God’s people to false teachers. False teachers are not simply a concern from outsiders hostile to the church**—it is a danger of rot from within. These teachers are not misled or misinformed;** they are liars meant to mislead, and they feel no shame about it. Take time to listen to this needed caution for the Church of today.
