The gospel in three words: God saves sinners
God – the Triune Jehovah, Father, Son and Spirit; three Persons working together in sovereign wisdom, power and love to achieve the salvation of a chosen people, the Father electing, the Son fulfilling the Father’s will by redeeming, the Spirit executing the purpose of the Father and Son by renewing. Saves – does everything, first to last, that is involved in bringing man from death in sin to life in glory: plans, achieves and communicates redemption, calls and keeps, justifies, sanctifies, glorifies. Sinners — men as God finds them, guilty, vile, helpless, powerless, unable to life a finger to do God’s will or better their spiritual lot.
— J. I. Packer
