Example 1: someone that was born and died before Jesus (such as Abraham).
All of the saints who died in the old testament era were saved through faith before they died.
These all
died in faith, not having received the promises, but having seen them afar off, and were persuaded of
them, and
embraced them, and confessed that they were strangers and pilgrims on the earth. Heb 11:13 (KJV)
faith is the substance of things
hoped for, the evidence of things
not seen. Heb 11:1 (KJV)
But without faith
it is impossible to please
him: for he that cometh to God must believe that he is, and
that he is a rewarder of them that diligently seek him. Heb 11:6 (KJV)
How can you "seek Him" after you die, when you are face to face with Him?
Example 2: someone that lived and died in an isolated community that had never heard of Christ.
God put them in those communities for the very purpose of them getting saved.
And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation; 27
That they should seek the Lord, if haply they might feel after him,
and find him, though he be not far from every one of us: Acts 17:26-27 (KJV)
Example 3: someone that struggled with Christian identity
I don't know what "Christian identity" is, but it sounds self-focused, as opposed to Savior-focused.
