Answer: The Colossians were infected with heresy.
Explanation: Paul wrote the letter of Colossians to contradict this infection. In Colossians, we find the greatest declaration of Christ’s deity and sufficiency found in Scripture. What Paul wrote then seems written expressly for our own day when so many “teachers” and “groups” are trying to rob Jesus Christ of His deity and sufficiency for our salvation through grace alone and our acceptance to God apart from works. It’s always time to check for infection in our thinking. We may discover that we have a concept about Jesus Christ, salvation, or the Christian life that is based on man-made tradition or philosophy instead of on Scripture. For “healthy living,” we will need to recognize that “infection” and give it up to accept the truth about Christ presented in God’s Word. That is the prescription for “healthy living.”
