Cannot believe the Gospel without believing that God is sovereign over all things

Grace in its whole progress must appear divine or sovereign; for when we lose sight of Sovereignty, we lose sight of Deity. It is of God that one man comes to the light, while another remains in darkness. It is of God that the love of one professor warms upon the trial and is accordingly crowned with consolation, while that of another waxes cold. - Robert Sandeman, An Epistolary Correspondence, pg. 89-90

Christ death was only for the elect alone

For the original grace that gave Christ to die for the elect, will as certainly have its full effect in bringing the whole redeemed Church to perfect holiness and happiness at last, as the word addressed to the first man and woman, which set in motion the course of nature (be fruitful and multiply) has been effectual to produce all the generations of men that have since inhabited the earth - If we enquire at the most highly favoured and best experienced Disciples, we shall find that their sense of things corresponds with this. - Robert Sandeman, An Epistolary Correspondence, pg. 90

Gospel believers cannot be said to be Antinomians no matter how one spends it.

Since I received your unexpected letter, my thoughts have been led upon various accounts diligently to enquire wherein the radical difference between us lies. As for those charges frequently alleged against the Doctrine I preach, that it is Antinomian, derogatory from the work of the spirit, destroys the comfort of believers, and sets aside the use of exhortations both to believers and unbelievers, &c. These are particulars too BAD to be easily credited by those who know my general character and principles. And when such things as these are objected to me, I feel or am intimately conscious that the sentiments I espouse are not in the least degree chargeable with any such consequences. Every one that rightly understands them will presently perceive, that they cannot be Antinomian, because the truth appears to be of such a nature, that a person who believes can have no enjoyment of himself, but in loving and obeying it from the heart according to the precepts of the gospel. They cannot be said to derogate from the spirit' work, because 'tis all along aver'd that the gospel can take no saving effect but by the necessary, efficacious Almighty and sovereign agency of the divine Spirit. Neither do they destroy the comforts of a believer, because they continually present to him a compleat and free Saviour, for his immediate relief, and assert that the Spirit of God witnesses to the genuine effects of the gospel appearing in his experience and conduct. - Samuel Pike, Free grace indeed! Set forth in a Scriptural view of the principle of grace wrought in the heart by the Spirit, pg. 2

The central difference between a believer and an unbeliever

The grand central difference, from whence arise all the others, may be thus express
He before thought, that there was a necessity for him to find some saving change or good disposition wrought in him, before he could have any peace in his conscience, or rest to his soul, from the perfect work of Christ presented in the gospel, and accordingly was distrest in his thoughts for want of perceiving it in himself, and therefore sought after it, and prayed for it, that he might obtain peace and hope towards God. And when he apprehended that he had found or obtained it, he laid the chief stress of his hope upon it. But now he finds relief to his conscience, not by discerning any favourable symptom about himself, but by understanding that blood of Christ is all sufficient and free, according to the divine testimony and this evangelical peace and rest thus obtained, becomes the root and spring of all that love and obedience, which distinguishes a believer from others. And so he now rejoices in Christ alone, having no confidence in the flesh. Phil 3.3. -Samuel Pike, Free Grace Indeed!, pg. 79

Definition of faith

We must then seek for some other method of distinguishing a false faith from a true, otherwise we shall be misled, as this to be feared many are, upon this way of stating it. What if after all these laboured complicated definitions of faith, it should appear, that the difference between one sort of faith and another, does not lie in any circumstances or consequences of it, but only in this, that what one believes is the truth, while what another believes is a falsehood, or some lie connected with the truth. - Samuel Pike, Free Grace Indeed!, pg. 41

The Gospel alone is the principle or foundation of all true holiness

But I must nevertheless, preach and proclaim this freeness of grace to fellow sinners, whether they will hear, or whether they will forbear. Firmly persuaded, that this is the true grace of God, and the only sort of grace that can suit their condition, and that can upon a right principle or foundation, either relieve their consciences, purify their hearts, comfort their souls or direct their conduct, under the influence of the blessed Spirit. Yea, and I must look upon the welcome reception of this grace, together with holy fruits thereof, to be the true and proper proof of genuine Christianity in heart and life. - Samuel Pike, Free Grace Indeed!, pg. 3

The Gospel is both absolute and immediate

The true grace of God as revealed openly in the word of the gospel is both absolute and immediate.
It is absolute, requiring nothing for the helpless sinner to their endeavor towards obtaining an interest in the divine favour for Paul says, if it be by grace, it is no more of works, otherwise grace is no more grace, Romans 11:6. And it is immediate, affording relief previous to the exertion of any act of ours for the apostle directly saying but if it be of works it is no more of grace, otherwise work is no more work. Nay, unless the grace manifested in the gospel by Jesus Christ has both these properties, it cannot be free indeed. For how should that be quite free, which leaves the poor sinner any thing to do to obtain it; or does not hold forth to him such information as is sufficient to afford him immediate hope of salvation by Christ. Upon the whole then, I cannot but apprehend that revealed grace has these properties so that a person no sooner understand and believes it, but he is enlightened and relieved thereby, and it becomes a principal of all holiness and consolation to him, being taught of God, by the Spirit of truth and grace. - Samuel Pike, Free Grace Indeed!, pg.2
