A subjective feeling of the presence of God is worse than useless as a measure of anything. If we rely on that for confirmation of God’s love we are simply relying on physical sensation.
Not sure what your post is telling us, but Christians possess a mind renewed by the Holy Spirit to understand God and His free gift of salvation.
Clearly, Mother Teresa is to be pitied. Her mind had not been renewed by the truth of Christ risen. She was bereft and without the indwelling Holy Spirit, according to her own words for 50 years right up until her death.
