Most people would know that a poor tree that has a bad root system has probably poor soil or lack of water to nourish the tree and it's fruit. Thereby from this we can deduce that we should be dealing with the hidden things of the tree to help it produce good fruit.
Luke writes of Jesus telling a parable about a fig tree that for 3 years bore no fruit to eat, the owner tells the vineyard worker to cut it down, but the worker says, "leave it alone for one more year and I will dig around it and fertilise it. If it doesn't bear fruit then you can cut it down"(Luke,13:6-9). This should make you happy because God is in the business of producing good fruit in His children and doesn't give up. The worker had to attend to the root system of the tree so that it could receive the nutrients and water it needed. But, notice that there was work to be done, firstly removing the dirt around it and then applying fertiliser and water. The dirt here is like the cares of this world, which needs to be removed before anything good will penetrate, and then the tree will come good(or maybe not, lets look a little deeper). What about the root system?, I mean what kind of root system would cause a tree to be barren? an immature root system maybe, or what about rotten roots or some type of root disease?
Each one of us has had particular lie/s told to us by the enemy very early in life so as to build a type of kingdom that he can control and set up for his own ends. For example, the foundational lie that grasped my heart as a child that I now see after many years of progressive stuff ups and failure, is that "I am no good" and "something is wrong with me". I carried this belief deep in my heart all the way into adulthood from my childhood. It was very well hidden and masked and as I got into my 20's and 30's it got worse with depression and despair and thoughts of suicide. If these negative lies of past bad roots are not dealt with effectively with the Truth of God's unconditional Love they will eventually manifest extremely bad fruit.
The lies I listened to and believed as a child through seemingly orchestrated events which the enemy used to produce fear in my life, caused a fear of rejection, self rejection, fear of nothing good will ever come my way and fear of being no good and unaccepted. These lies progressively became worse and worse as more lies and fear were added and laid upon the foundation already believed as a child. I guess there are many variants to the lies the enemy tells people growing up and will use whatever situation is at hand to build himself a home. If your parents attempted to abort you as a baby, the lie would be"I'm not meant to be here, I don't belong". If your parents wanted the opposite sex as a baby, the lie would be,"I am wrong, something is wrong with me". If you feel one or both parents abandoned you, the lie would be"I am no good, I am not worth it". With all these lies the fear comes as rejection and is a deep seated painful root system that causes God's people to strive as the world does for approval and acceptance. Jesus said His yoke is easy and burden is light and came that we might have life more abundantly. God's love for us is real and tangible if it can get through the net of lies and fears and reach into the depths of the heart.
Satan can tell no truth, this is what Jesus says about him : "...not holding to the truth, for there is no truth in him. When he lies he speaks his native language, for he is a liar and the father of lies". John,8:44 NIV
How does he do it?
If the lie/s were accepted in childhood at the heart level it can change part of the person's character and we say,"That's just the way so and so is". But, so and so is like that because the lie flawed their character when fear entered and required a defensive structure to protect the heart from the pain of the lie/s. The lie can only be overcome by the Truth in the Word of God and the fear only overcome by the perfect Love of God. The pure love of God will not penetrate the heart fully until the lie is recognized, repented of and replaced with the truth, and the lying spirit along with the fear spirit is cast out. When the Kingdom of God is planted firmly in ones heart, it's work is to overcome the old kingdom fully and bring glory to our Father in heaven as a righteous tree that stands as a spectacle in this world and bring Christ's light and love to it. God's plan is for you is to have all surpassing peace through Christ Jesus, that means all surpassing peace in your mind and soul as well as your heart. God has not given his children a spirit of fear, but of courage and sound mind....AMEN.
