The word of God is quick and powerful and sharper than any two edged sword piercing even to the dividing asunder of soul and spirit and of the joints and marrow and is a discerner of the thoughts and intents of the heart Hebrews 4:12
Jesus teaches us to Love the lord your God with all your heart and with all your soul and with all your mind and with all your strength and love your neighbor as yourself (Mark 12:30-31)
