Systematic Theology, Day 6

“The Gospel, strictly taken, differs from the Law, in that, 1. The Law considers us as God’s rational creatures and subjects, who were originally formed with sufficient abilities perfectly to obey it, and hence directs and binds us to have such abilities, and to exercise them in a proper manner towards God, ourselves, and our neighbours, as our duty (Matt 22:37-39); but the Gospel considers us as sinful and self-ruined men, graciously pitied by God and declares what He, according to His infinite mercy and grace, has done, prepared for, and offers to be, and do to us (Isa. 42:6-7, 49, 53-55, Ps. 22, 68, 146). Hence its offers and invitations continue to believers while their sinfulness remains, and no longer condemns.”

“IV. The Harmony of the Law and Gospel is their suitableness and subserviency to each other:  the Gospel promises, offers, and gives to sinful men every thing which the Law, in any form, demands of them.  It provides them with their righteousness of the Son of God, which answers and magnifies all the demands of the Law, as a broken covenant: and lays an effectual foundation of universal, and at last perfect obedience to it, as a rule.  Nay, it promises preparation for, assistance in,  and a gracious reward of every duty which the law, as a rule,  requires…”

Systematic Theology, Day 5

“Though Christ effectually save none but His Elect (Eph. 5:23). He is by Divine Appointment, grant, and office the Savior of the World, fit for all sinful men, and to whom they are all warrented by God to apply for salvation (John 4:42, 1 John 4:14). His salvation is a common salvation (Jude 3) and his gospel is grace, which bringeth salvation in offer to all men that hear it (Titus 2:11, 1 Tim 1:15). If Christ’s administration of the new covenant were not thus general and indefinite, some men would have no more warrant to hear the Gospel, or believe in and receive him for their salvation, than devils have, contrary to Mark 16:15-16. ” –John Brown of Haddington, Systematic Theology pg.  244
