Satan has spies. Enemy agents who oftimes ignorantly think they are doing right when in fact they are serving the purposes of the evil one. These are what our Savior referred to as tares in Matthew 13. Tares look like wheat in the field. Until harvest time, it is hard to distinguish the difference. Of course when the wheat has matured, the head is full of grain that is fit to make bread. Unlike the tares that will still be standing tall in the field, wheat will be bowed over from the weight of the seed it bears. At the time of the harvest, it will be very easy to tell the differnce. Why are the tares allowed to grow with the wheat? Remember, Jesus said in the parable to let the tares grow with the wheat until harvest time and then to gather the tares first and throw them into the fire to be destroyed. When Satan fails to get us to walk in his way, he sows "tares' in the field that the Lord has sown with good seed. Read the parable for yourself. Jesus explains just who sows the bad seed in a field sown with wheat. Paul told the Corinthians in his first letter chapter 11 verse 19 For there must be also heresies among you, that they which are approved may be made manifest among you. So, even though these enemy agents who spy out our liberty, who are always running to and fro stirring up all kinds of trouble, who either knowingly or ignorantly cause strife...whether they realize it or not, they are serving the Lord's purpose. It took me along time to really understand this. So, when these agents of evil come into your midst, praise God that HE has a plan.
