HOW TO PREPARE THE HEART TO RECEIVE
Your heart has learned a lot of natural things in this World because it has been schooled here. Your heart has no idea of spiritual reality and this is why it is hard for the heart to believe in spiritual reality or to believe God for miracles such as healing, gifts of the Spirit and so on.
The reason why we are full of unbelief towards God is because the heart is not trained on spiritual reality. The heart is carnal and it needs training towards reality of the Spirit.
We must school the heart with the Word of God to awake to the things of God just as we trained it about the things of this World. If you want to clear unbelief out of your heart, then you must educate the heart with the Word of God which is the Spirit. Until the heart is trained, believing God will be hard for you. Get this material and it will open your heart how to receive from God effortlessly.
