"Salvation," "Deliverance," "Redemption" is the proclamation to the nations of God's Will by all His Messengers - the Patriarchs, the Prophets, Jesus Christ, the Apostles, and all the Righteous, who so dedicated their lives to delivering the nations from unrighteousness and the commission of sin.
"Salvation" is the process of man's knowing and doing God's Will, His Commandments, which rescues him from the captivity of a morally and spiritually corrupt mind, which delivers him from the sinful inclinations of the flesh, which enslave the spirit, soul and body, which saves him from following false religious beliefs and various dogmas, which frees him from religious fanaticism and pharisaism, and which also delivers him from committing iniquities and their consequences.
"Salvation" is the avoidance of trouble and destruction by righteous living people by their doing the Will of God, His Commandments.
