Where there are the "little foxes" in our vineyards, we must take action to seek them out and remove them from our daily lives. If the root is holy, so are the branches." God has called us to be holy, and when it comes to holiness, God does "sweat the small stuff"-and so must we!
Our Savior's response teaches us that the promises found in the psalm are not automatic and unconditional. You shall not tempt the LORD your God, meaning God cannot be forced to act on our behalf. He does not take kindly to humans testing Him to see if He will respond. Save truthful repentance, we will reap what we sow.
Faith remembers truth but also responds emotionally to a wonderful, dynamic, gracious, and powerful Personality who is our Friend. So, all we must do is to follow His lead, and we will find rest from all our burdens in His Kingdom.
