Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother's were righteous.
NIV
[And] not be like Cain who [took his nature and got his motivation] from the evil one and slew his brother. And why did he slay him? Because his deeds (activities, works) were wicked and malicious and his brother's were righteous (virtuous).
AMP
Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous.
KJV
No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him.
NIV
No one who abides in Him [who lives and remains in communion with and in obedience to Him--deliberately, knowingly, and habitually] commits (practices) sin. No one who [habitually] sins has either seen or known Him [recognized, perceived, or understood Him, or has had an experiential acquaintance with Him].
AMP
Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
KJV
Dear friends, if our hearts do not condemn us, we have confidence before God
NIV
And, beloved, if our consciences (our hearts) do not accuse us [if they do not make us feel guilty and condemn us], we have confidence (complete assurance and boldness) before God
AMP
Beloved, if our heart condemn us not, then have we confidence toward God.
KJV
