"I now confided all my sorrows and perplexities to my mother. She tenderly sympathized with and encouraged me, advising me to go for counsel to Elder Stockman, who then preached the advent doctrine in Portland. I had great confidence in him, for he was a devoted servant of Christ. Upon hearing my story, he placed his hand affectionately upon my head, saying with tears in his eyes: “Ellen, you are only a child. Yours is a most singular experience for one of your tender age. Jesus must be preparing you for some special work.” 1T 29.2"
"But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Gentiles, and kings, and the children of Israel:"
Both passages relate to someone being chosen for a specific purpose. Acts 9:15 explicitly states Paul is chosen, while the EGW passage suggests Ellen is being prepared for a special work. The thematic parallel is the idea of divine selection and preparation.
"And the Lord came, and stood, and called as at other times, Samuel, Samuel. Then Samuel answered, Speak; for thy servant heareth."
Both passages involve a young person receiving a divine calling or message. Samuel hears God's voice, and Ellen receives encouragement and a sense of destiny from Elder Stockman. The parallel lies in the early recognition of a special purpose.
