The words are by Howard Arnold Walter, he was from Connecticut, very talented, he graduated from Princeton in 1905 and wrote the hymn in 1906 whilst studying in Japan. He sent it home to his mother who forwarded it to Harper's Magazine, who published it. In 1912 he went to serve the Young Men's Christian Association in India, and was told he had a terminal heart defect, his response was ' then I should get to work at once.' He died 6 years later, his last words were 'Christ, I am ready'.
There is a third verse which I didn't know but looked up today:
I would be faithful through each passing moment,
I would be constantly in touch with God;
I would be strong to follow where He leads me,
I would have faith to keep the path Christ trod.
And so he did.
