1 Chronicles 28:9 (NIV) And you, my son Solomon, acknowledge the God of your father, and serve him with wholehearted devotion and with a willing mind, for the LORD searches every heart and understands every motive behind the thoughts. If you seek him, he will be found by you; but if you forsake him, he will reject you forever.
Matthew 22:37 (NIV) Jesus replied: "Love the Lord your God with all your heart and with all your soul and with all your mind."
1 Corinthians 14:14-15 (NIV) 14 For if I pray in a tongue, my spirit prays, but my mind is unfruitful. 15 So what shall I do? I will pray with my spirit, but I will also pray with my mind; I will sing with my spirit, but I will also sing with my mind.
