Laurie, you are right about a spirit and soul salvation, but there is also the salvation of the body. We are a three-part being: body, soul, and spirit, just as God also is a trinity. The whole process of salvation, the three parts, is given to us in the three main Feasts of the Lord.
 
There is the  Passover experience, in which we are justified, and our spirits are sealed with the blood of Jesus, just as the Israelites were sealed with the blood of the passover lamb. This is something that can never be lost. This is what we call the salvation of the spirit. This is done by the work of the Holy Spirit, not of ourselves.
 
But the Israelites did not stop at Passover, and neither do we. We are to move on to the Pentecost experience, just as they did. This is where we obtain salvation of our souls, and we become reconciled to God. This reconciliation experience is when two enemies become  reconciled to one another, or they are of one accord. This is something that we must work out, and comes with a deeper, willing walk of obedience that comes from hearing the voice of the Lord, and obeying out of love. Some Christians are content to stop here, and not move on to hear the voice of the Lord for themselves, just as the Israelites preferred that Moses go up Mt Sinai and hear the voice of God and then tell them what He said.
 
Then there is the ulitmate Tabernacles experience, which we have not arrived at yet. This will be the salvation of the body, whether we are alive and remain, or whether one has already died in Christ and that body will be resurrected. Not all the Israelites crossed over into the promised land, and not all will experience the glorification of their mortal body.  This is only for the overcomers, the bride, and is to which Paul referred in his writings as looking for the prize or reward at the end of the race.
 
This is a very simple explanation, and for lack of time and space, if there are those who wish to read more, please send me an email at the address embedded in my name above.
