“Therefore, since Christ suffered in his body, arm yourselves also with the same attitude, because whoever suffers in the body is done with sin.” (I Peter 4:1 NIV)
Those who call themselves Christians ought to live as Christ live. Therefore we should choose suffering over sin, because sin is not an option for us. If we do what is right in the face of difficulty than our “body is done with sin” because we have overpowered sin and been granted victory over it.
Of course the power to conquer sin does not come from ourselves. It can only come from God. It is given to us if we repent and believe in Jesus Christ the Son of God. Just as God raised Jesus from the dead, so also He can also save us from sin and spiritual death.
