What a great practical topic on those sneaky sly little foxes who are up to no good. Their nature is derived from Lucifer himself. Their purpose is to hinder and even try to destroy our personal relationships with God, family, friends and the church family. These little foxes like to come out in the darkness because they know the light will expose them of their evil intentions.They see an opening in the fence of defense and they will dig and dig until they sneak in and eat the fruit of the vine in our lives.
The Bible states that Jesus is the true vine, and God the Father is the Gardner and we are the branches. As branches we must abide in Him so we can remain connected to Jesus so in turn, produce much fruit. Galatians 5 points out the fruit Jesus expects from us...  But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness,  gentleness and self-control. Against such things there is no law. These are the graces which should characterize us as Christians.
The sins of the flesh are the gross sins of adultery, murder, blasphemy, drunkenness etc. The sins of the spirit are the little foxes that can spoil the vines. Some examples are; pride, being offended, anger, bitterness, lying, and gossiping. Vines represent your relationship with God, family, friends and the church family. These little foxes invade us through the wrong things we think, the wrong things we say, and the wrong things we do.
We counter with the blood of the Lamb. The Lord Jesus has already defeated him upon Calvary and we are more than conquerors. When these little foxes come around we can light their tails with the Holy Ghost fire and send them back to where they came from! That’s what Samson did to the enemies of his days.
We need to go back to the basics by committing to His Word, and by praying and fasting. It starts with me and my house, you and your household, which makes up our local Calvary Temple Church.
Catch for us the foxes, the little foxes that ruin the vineyards, our vineyards that are in bloom. Song of Songs 2:15 NIV
So beware of the little foxes that can hinder your relationship with God, family, and friends.
