5 You know that He was revealed so that He might take away sins, and there is no sin in Him.
Jesus’ main purpose on earth was to die in our place and to rise from the grave, so that sin can be dealt with. Once the debt of sin has been paid for, forgiveness from the Father can be extended to anyone who accepts Jesus as their Lord.
The payment for the sins of the whole world demanded a person to be without sin and to stay that way. Only Jesus was and is without sin and even in the face of Satan’s temptations, Jesus was triumphant.
