Chapter 6 brings up the issue of Laziness. In verse 6, the example that is given is the ant. Think about the ant.
The ant is punctual in his work (works without being told to) - How many Christians can that be said of today? As a pastor, it sometimes feel as if you have to push and poke some Christians just to get them to show up to worship, much less serve and work for the Lord. As a born-again believer, we should have a desire to serve God without being told.
The ant is purposeful in his work - Many Christians live a purpose-less life. They go about every day never considering the greater purpose of their life, never considering tomorrow and what it may hold. Just as the ant laid up food for the winter, we should be laying up treasures in heaven.
There are many other great truths here in this chapter, but I will let some of you comment on those. Looking forward to your thoughts.
