The church has the charge of the world entrusted to it. When Christ had finished his work on earth, and went to heaven to carry it on there, he spoke of two powers to whom the continuation of the work on earth was to be committed.
He spoke of the Holy Spirit, who, equally with God himself and the
Father, should come in his name to convict the world of sin, and be a
divine power in his disciples to reveal himself in them, and so make
them witnesses for him to the ends of the earth.
He spoke of his disciples as those whom he sent into the world, even as
the Father had sent him. Just as entirely as he had lived to do the
Father’s will in saving men and women, was his Spirit to do that work
too. And just as wholly as the Spirit was to be devoted to that work,
was the body, the church, to be set apart for it too.
The whole body of believers, and every individual believer, was to be
like Christ, the light of the world, placed in the world with the one
definite, exclusive object of enlightening its darkness, and bringing
men and women out of darkness into light.
