“..This is generally the view of one not filled with the Spirit...”
It is a direct scripture quote. Therefore this is the truth imparted by His Spirit.
One can read Scripture without correctly discerning its meaning.
Ephesians 1:3-10 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, 4 even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love 5 he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, 6 to the praise of his glorious grace, with which he has blessed us in the Beloved. 7 In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, 8 which he lavished upon us, in all wisdom and insight 9 making known to us the mystery of his will, according to his purpose, which he set forth in Christ 10 as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.
When Jesus died on the cross, He said, "It is finished.".
Suffering does not purify from sin. It has other work to do in the believer.
