There are no instances of "personal" in the scriptures but your comments are reflective of theology in the modern world, it being wholly personal in nature.

Among the terminology used in Scripture to describe the spiritual dynamic of Salvation are: “pick up your cross and follow Jesus”, “be born again”, be “seed in good soil”, “justified by faith”, “saved by grace”, at “peace with god”, “in Christ”, have your “name written in heaven”, be one of the “chosen elect”, have “Christ in you.”
Many of the above can be described as personal in both word and especially in deed. But no, the exact term is not in scriptures. However the personal lives recorded demonstrate such. For example, being chosen by The Son of God as a disciple is quite a personal experience.
Mary Magdalene at the empty tomb and then being the first to encounter the Risen Christ was quite personal. Thomas declaring “My Lord and My God” again quite a personal experience. Pentecost. Personal. Being baptized...personal.
I agree the term itself is not specifically found in scriptures and as you noted the use of “my” God is personal in nature.
For we know:
If you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. 10 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. 11 For the Scripture says, “Whoever believes on Him will not be put to shame.” 12 For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him. 13 For “whoever calls on the name of the Lord shall be saved.”(Romans 10)
Everyone is judged just as “personally” ... one-by-one ... whether that person is from the modern world, the ancient world or the antediluvian world ... :-) ...
