See EGW comment on 1 Corinthians 2:1-5.

 What a humiliation it was to Paul to know that all the time he was using his powers against the truth, thinking he was doing God’s service, he was persecuting Christ. When the Saviour revealed Himself to Paul in the bright beams of His glory, he was filled with abhorrence for his work and for himself. The power of Christ’s glory might have destroyed him, but Paul was a prisoner of hope. He was made physically blind by the glory of the presence of Him whom he had blasphemed, but it was that he might have spiritual sight, that he might be awakened from the lethargy that had stupefied and deadened his perceptions. His conscience, aroused, now worked with self-accusing energy. The zeal of his work, his earnest resistance of the light shining upon him through God’s messengers, now brought condemnation upon his soul, and he was filled with bitter remorse. He no longer saw himself as righteous, but condemned by the law in thought, in spirit, and in deeds. He saw himself a sinner, utterly lost, without the Saviour he had been persecuting. In the days and nights of his blindness he had time for reflection, and he cast himself all helpless and hopeless upon Christ, the only one who could pardon him and clothe him with righteousness (Manuscript 23, 1899).

 Always the Lord gives the human agent his work. Here is the divine and the human cooperation. There is man working in obedience to divine light given. If Saul had said, Lord, I am not at all inclined to follow your specified directions to work out my own salvation, then should the Lord have let ten times the light shine upon Saul, it would have been useless. It is man’s work to cooperate with the divine. And it is the very hardest, sternest conflict which comes with the purpose and hour of great resolve and decision of the human to incline the will and way to God’s will and God’s way.... The character will determine the nature of the resolve and the action. The doing is not in accordance with the feeling or the inclination, but with the known will of our Father which is in heaven. Follow and obey the leadings of the Holy Spirit (Letter 135, 1898).
