In verse 18, Paul expressed his sorrow over the plight of unsaved false teachers. In this verse, he offers four descriptions regarding their behaviors. First these false teachers are not simply Christians who misunderstood a portion of the gospel. These are unsaved individuals, rejecting the gospel itself, and who will experience destruction apart from faith in Christ. Second, for false teachers, Paul notes their focus on greed. Many false teachers, then and now, seek money in order to make a profit (1 Timothy 6:5), rather that truly serving the Lord. In contrast to Christ-like believers, false teachers are more concerned with their own desires than the needs of other people (Romans 16:18).
