Richard Sibbes (1577-1635), pastor and theologian has a few words on the sufficiency of Christ’s offering to the Father, and the trinitarian shape of the gospel:
What a support to our faith is this, that God the Father, the party offended by our sins, is so well pleased with the work of redemption! And what a comfort is this, that seeing God’s love resteth on Christ, as well pleased in him, we may gather that he is as well pleased with us, if we be in Christ! For his love resteth in whole Christ, in Christ mystical, as well as Christ natural, because he loveth him and us with one love. Let us, therefore, embrace Christ, and in him God’s love, and build our faith safely on such a Saviour, that is furnished with so high a commission. See here, for our comfort, a sweet agreement of all three persons: the Father giveth a commission to Christ; the Spirit furnisheth and sanctifieth to it; Christ himself executeth the office of a Mediator. Our redemption is founded upon the joint agreement of all three persons of the Trinity. (Richard Sibbes, trans. Grosart, “Works of Richard Sibbes: The Bruised Reed and Smoking Flax,” 42-3)
What amazing thoughts! Did you notice in the first paragraph how Sibbes highlights the function that our union with Christ has before the Father. We are loved by the Father, with the same love that He loves His Son, Jesus, with. Let that reality sink in, meditate upon how intimate in fact you are with the Father, through the Son, by the Holy Spirit! We are truly represented, and known to the Father, because of the redemptive work and mediatorial Priesthood of the Son. Come boldly to the Father, come as if you are His dearly beloved Son . . . because You are! We have been enveloped into the intratrinitarian life of the Father, Son, and Spirit; snatched out of the idolatry and slavery of self-love, and brought into the union and communion of HIS love. LOVE BOLDLY!
