Disputations today has a brief column (see 11:02) regarding the necessity of saving your own soul before you proceed to that of others. This immediately put me in mind of A Pilgrim's Progress in which Christian is advised likewise. Once might also consider that Jesus kind of advised the same thing "Take the beam from out thine own eye before thou regardest the mote in thy brother's." There are other places where such advice is made explicit as well. Looking to your own salvation is the only way to help show someone the path to his or her own.
Now, admittedly, this can become toxic and obsessive. We could be so controlled by worrying about our salvation that we find ourselves incapable of acting. It becomes morbid. However, it is a good idea to be certain you are at least aware of the path you should be walking (even if you aren't doing a particularly good job of it) before you try showing others the way they should be going.
Even though it is a work of Puritanism at its height, a Pilgrim's Progress is worth a look--even if only to better understand Lewis's A Pilgrim's Regress.
