The answer
Your soul is who you are as a person, a human being. Every aspect of your existence is intricately interwoven. The heart has the function of your emotions and your mind has the function of our thoughts and reasoning.The Holy Scripture refers to the word “soul” as the whole person (as in 1 Peter 3, when he spoke about eight souls that were saved from the flood); or to the human spirit only; or the soul only (as in 1 Thessalonians 5); or to the heart (as when the Lord said, "My soul is sorrowful unto death"); or to the desires of the person, etc.
The heart and mind are parts of the soul, but when the Lord said, “And you shall love the LORD your God with all your heart, with all your soul, with all your mind, and with all your strength” (Mark 12:30), He meant, from all your emotions, all your desires, all your thinking, and all your strength.
