We are then, I say, to eye it, to believe it, to receive it, as in him; the issues and fruits of it being made out to us through Christ alone. Though there be no light for us but in the beams, yet we may by beams see the sun, which is the fountain of it. Though all our refreshment actually lie in the streams, yet by them we are led up to the fountain. Jesus Christ, in respect of the love of the Father, is but the beam, the stream; in which though actually all our light, our refreshment lies, yet by him we are led to the fountain, the sun of eternal love itself. Would believers exercise themselves in this, they would find it a matter of no small spiritual improvement in their walking with God.
