'Mind' in the Bible

John the Baptist appeared in the wilderness preaching a baptism of repentance for the forgiveness of sins [that is, requiring a change of one’s old way of thinking, turning away from sin and seeking God and His righteousness].

and saying, “The [appointed period of] time is fulfilled, and the kingdom of God is at hand; repent [change your inner self—your old way of thinking, regret past sins, live your life in a way that proves repentance; seek God’s purpose for your life] and believe [with a deep, abiding trust] in the good news [regarding salvation].”

When His own family heard this they went to take custody of Him; for they were saying, “He is out of His mind.”

They came to Jesus and saw the man who had been demon-possessed sitting down, clothed and in his right mind, the man who had [previously] had the “legion” [of demons]; and they were frightened.

But turning around [with His back to Peter] and seeing His disciples, He rebuked Peter, saying, “Get behind Me, Satan; for your mind is not set on God’s will or His values and purposes, but on what pleases man.”

and you shall love the Lord your God with all your heart, and with all your soul (life), and with all your mind (thought, understanding), and with all your strength.’
