Exactly. The picture is the redeemer is redeeming someone that is already in his family. The book of Ruth is not a book about everlasting life, but what happens to a saved person after they are saved.The Kinsman redeemer is a "type" of Christ.
Everlasting life merely starts your journey it is not the end of the journey or we need not stick around any longer.
Very early on in the book we get a picture of two types of Christians. One type runs the race of the faith and the other turns back. Then at the end of the book we see that only one type of Christian becomes part of the bride. The other does not.
If we are not a part of the bride of Christ we will not rule and reign with Him in His coming kingdom.
