SN basically much of the New Testament is talking about the salvation of the soul not the salvation of the spirit.
The salvation of the soul is directly tied into acceptance of the coming kingdom. That is the big misconception when it comes to the message that John the Baptist, Christ, the Apostles and early disciples were delivering. They weren't delivering a message of salvation by grace, but they were delivering a message of salvation in regard to the kingdom of the heavens (Matthew 13 specifically, but every other place that kingdom of heaven is used in Matthew it is actually plural with the definite article "the" which means the correct rendering would be the kingdom of the heavens - this can also be found in John chapter 3 I believe in one of the earliest manuscripts although it is not translated that way, but kingdom of God).
You can also see that specific wording in James 1:21 and I Peter 1:9.
When we are saved by grace through faith we are made alive spiritually, but our spirit which is now in light is separated from our soul which is still in darkness. And since we are made alive spiritually we are now in a position to entertain the gospel of the glory of Chirst, which is how Paul refers to this message. Before we were made alive spiritually it was impossible to entertain this message, because it is a spiritual message and spiritually dead folks can not understand spiritual things.
We are made alive spiritually so that we can understand the rest of the good news.
