"Justification" is the forgiveness of one's sins to a person who obeys God's Commandments, a confirmation of the efforts he has made to acquire and maintain his righteous life.
"Justification" is also the deliverance from the remorse of conscience, the man's mental, emotional and spiritual peace of mind that comes from the cessation of his violation of God's Will and the receiving, acceptance of the blessings of the cessation of the trial of the consequences of its violations.
