Sorry, that is incorrect.

This is true; however, there is more than one correct answer!

Throughout the Bible, as the seat of mankind’s deepest convictions, beliefs and volitional will, it is the heart that is recognized as the root of mankind’s problem. As representing the essence of a man, the heart is the primary focus of God’s commands, calling and home for the Holy Spirit.

"Moreover the LORD your God will circumcise your heart and the heart of your descendants, to love the LORD your God with all your heart and with all your soul, so that you may live." (Deut 30:6)

"When anyone hears the word of the kingdom and does not understand it, the evil one comes and snatches away what has been sown in his heart…" (Matt 13:19)"
