A hungry wolf, scouting a caribou herd, would never take on a healthy bull. He looks for one of two kinds of stragglers. Either a calf that has become separated from its mother or a caribou that is sick and can no longer keep up with the herd. In each case the wolf takes advantage of weakness to isolate them and kill them off.
When a cult is looking for someone to bring in to their fold they follow the same strategy. They don’t take on Christians who are strong and mature, but those who are weak and isolated. That was Paul’s fear that weak and isolated Christians would be captured and separated from the joy of knowing Jesus and settle for that which doesn’t save us. But healthy Christians can resist. This is because they are “rooted and built up in Jesus.” They have a foundation that can’t be moved and they are continuing to build on that foundation. They are “strengthened in the faith as . . . taught.” It is difficult to deceive the believers who know the truth taught in the Bible. They are “overflowing with thankfulness.” Like a river their relationship with Jesus grows wider and deeper all the time.
Father, whenever I base my life on what is not biblically true, set me straight. Amen.
