John 17:18: Ambassador of the Most-High

Ambassador of the Most-High
Thy Father sent Thee from the sky
To make His truth and mercy known;
And every chosen instrument
By Thee into the world is sent.
To carry Thy great business on;
They of Thy work obtain a part,
And labouring sinners to convert,
Their ministerial task fulfil,
Ready their lives to sacrifice
(That precious souls may reach the skies)
And with their blood the record seal.
