Fourth. If man should be saved any other way than by grace, God would be disappointed in his design to cut off boasting from his creature; but God's design to cut off boasting from his creature cannot be frustrated or disappointed; therefore he will save man by no other means than by grace; he, I say, hath designed that no flesh should glory in his presence, and therefore he refuseth their works; "Not of works, lest any man should boast." "Where is boasting then? It is excluded. By what law? of works? Nay; but by the law of faith" (Eph 2:8,9; Rom 3:24-28).
Fifth. God hath ordained that we should be saved by grace, that he might have the praise and glory of our salvation; that we should be "to the praise of the glory of his grace, wherein he hath made us accepted in the Beloved" (Eph 1:6). Now God will not lose his praise, and his glory he will not give to another; therefore God doth choose to save sinners but by his grace.
Sixth. God hath ordained, and doth choose to save us by grace, because, were there another way apparent, yet this is the way that is safest, and best secureth the soul. "Therefore it is of faith, that it might be by grace; to the end the promise [the promise of eternal inheritance, (Heb 9:14-16)] might be sure to all the seed" (Rom 4:16). No other way could have been sure. This is evident in Adam, the Jews, and, I will add, the fallen angels, who being turned over to another way than grace, you see in short time what became of them.
To be saved by grace supposeth that God hath taken the salvation of our souls into his own hand; and to be sure it is safer in God's hand than ours. Hence it is called the salvation of the Lord, the salvation of God, and salvation, and that of God.
When our salvation is in God's hand, himself is engaged to accomplish it for us. 1. Here is the mercy of God engaged for us (Rom 9:15). 2. Here is the wisdom of God engaged for us (Eph 1:7,8). 3. Here is the power of God engaged for us (1 Peter 1:3-5). 4. Here is the justice of God engaged for us (Rom 3:24,25). 5. Here is the holiness of God engaged for us (Psa 89:30-35). 6. Here is the care of God engaged for us, and his watchful eye is always over us for our good (1 Peter 5:7; Isa 27:1-3).
What shall I say? Grace can take us into favour with God, and that when we are in our blood (Eze 16:7,8). Grace can make children of us, though by nature we have been enemies to God (Rom 9:25,26). Grace can make them God's people which were not God's people (1 Peter 2:9,10). Grace will not trust our own salvation in our own hands—"He putteth no trust in his saints" (Job 15:15). Grace can pardon our ungodliness, justify us with Christ's righteousness; it can put the spirit of Jesus Christ within us, it can help us up when we are down, it can heal us when we are wounded, it can multiply pardons, as we, through frailty, multiply transgressions.
What shall I say? Grace and mercy are everlasting. They are built up for ever. They are the delight of God. They rejoice against judgment. And therefore it is the most safe and secure way of salvation, and therefore hath God chosen to save us by his grace and mercy rather than any other way (Isa 43:25; Rom 3:24,25; Isa 44:2,4; Psa 37:23; Luke 10:33,34; Isa 55:7,8; Psa 136; 89:2; Mal 3:18; James 2:13).
Seventh. We must be saved by the grace of God, or else God will not have his will. They that are saved are "predestinated unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, to the praise of the glory of his grace" (Eph 1:5,6).
1. But if it be his will that men should be saved by grace, then to think of another way is against the will of God. Hence they that seek to establish their own righteousness are such as are accounted to stand out in defiance against, and that do not submit to, the righteousness of God—that is, to the righteousness that he hath willed to be that through which alone we are saved by grace (Rom 10:3).
2. If it be his will that men should be saved through grace, then it is his will that men should be saved by faith in that Christ who is the contrivance of grace; therefore they that have sought to be justified another way have come short of, and perished notwithstanding, that salvation that is provided of God for men by grace (Rom 9:31-33).
