There is no "personal savior" in the scriptures; the scriptural reference is to call God "my Savior" or "Savior of the world." The name change for Cephas was significant, because as with Abram and wit Jacob, the LORD built upon Cephas, just as Jesus said that he would, for those who have ears to hear and are not blinded.
We’re born one-by-one and we are saved one-by-one. Each one who is saved is a special creation of God. That’s unique and personal.
