I don't understand your aversion to the word "personal". I've already shown you throughout Scripture where this concept is well attested to. That you consider the term "foolishness" smacks of pettiness and nitpicking. The doctrine of sola Scriptura also is not impugned by wording ideas and thoughts in vernaculars or in a way that people fully grasp the meaning. Jesus was all over the place preaching the need for people to have a personal relationship with God rather than trusting in a community or familial one. We probably all know people who say they are Christian, but who, through their actions and words, show that there hasn't been a personal commitment to Christ.
One more thing, sola Scriptura does not mean every single word MUST be in Scripture, just that it is taught and proven BY Scripture. So, no, trusting in Jesus Christ as my personal savior is HARDLY a "marketing technique" invented by Billy Graham. He'd probably LOL if he heard that.
It is completely scriptural to refer to God as "my Savior." Inserting "personal" into the phrase adds nothing to it. It is, at best, redundant. I think it is a deliberate marketing campaign to make sales numbers. It isolates it to a personal decision where each individual is their own overseer, totally in charge of what scriptures they admit, what interpretations they allow, and what "being saved" means to them personally. Afterward comes the "make Him The Lord of your life" pleas. Did I mention baptism ? No, where does the argument to make the LORD Jesus Christ one's personal savior emphasize baptism ? It doesn't; it is a multilevel marketing term. Wherever your journey takes you is fine, no membership to a community of baptized believers ? No problem, you keep on truckin'. The Baptist model of "win 'em, wet 'em, and work 'em" is more scriptural but makes for a poor slogan in a soul winning campaign.

If that is true you will confess blessed Mary is the mother of God with us, which testifies to us from Isaiah and Matthew. Do you confess or deny it ?
