1 John 3:9-10

No one who is born of God [deliberately, knowingly, and habitually] practices sin, because God’s seed [His principle of life, the essence of His righteous character] remains [permanently] in him [who is born again—who is reborn from above—spiritually transformed, renewed, and set apart for His purpose]; and he [who is born again] cannot habitually [live a life characterized by] sin, because he is born of God and longs to please Him. By this the children of God and the children of the devil are clearly identified: anyone who does not practice righteousness [who does not seek God’s will in thought, action, and purpose] is not of God, nor is the one who does not [unselfishly] love his [believing] brother.
