Salvation of Man
There is only one place in Scripture where the question is actually asked, What must I do to be saved..? and the answer is given clearly and simply, Believe on the Lord Jesus Christ and you shall be saved. The spirit of man which was born dead in trespasses and sins is saved simply by believing on the Lord Jesus Christ as our sacrifice for sin. But our initial salvation (our salvation of the spirit) is of course the first step on a life journey for the salvation of the soul of man, for once we have been eternally saved we are told by Paul, in Philippians 2:12, that we must work out our own salvation. This aspect of salvation is called sanctification and is ongoing throughout the whole of our whole Christian life.
