God created us as spirit beings to live in a body. Our soul also lives in our body and is separate from our spirit. However many interchange the spirit and soul. 1 Thessalonians 5:23 clearly states that we are body, soul, and spirit. In Hebrews 4 the Word of God is able to separate the soul from the spirit. Therefore clearly we can see there is a separation between the soul and the spirit. Our spirit was redeemed through the born-again experience. Our souls are being redeemed through our minds being renewed. Our soul is made up of our thoughts, feelings, and will.
Mind Full
To be mind-full is to be full of facts about life. We can have a lot of facts but lack wisdom. Facts are not the truth. Truth is in a person, Jesus. He is the Truth and the Life. When we have the Truth we are able to walk in the Truth. The Holy Spirit was sent to reveal the Truth to us. Truth is of the Spirit and therefore we cannot know the truth without the Spirit. The facts may lead us to the truth. Being able to discern the truth is a gift of the Spirit. Many can be full of facts but fail in the long run because they are unable to know the truth. I might have a lot of head knowledge but lack in heart knowledge. Knowledge of the heart is of a different realm to head knowledge.
Heart Full
Heart knowledge is of the Spirit. In the spirit, we are able to connect with God who is spirit. We become one with Him and are called sons of God. In the Spirit, we are able to discern behind the head knowledge and detect the spirit behind the knowledge. In this way, we are able to transcend the different sources or narratives in the world that seek to confuse and deceive us. In the world, the god of this world, will try and deceive us and keep us from the truth. This is why we see so much delay and deception that keeps us from knowing the truth. Let us keep our eyes fixed on Jesus and He will keep us steadfast in Him till the end.
