Exam. 6. Art thou born again? Then thou knowest that God hath given thee thy faith that thou hast in his Son: Then thou art to say through grace, there was a time in which I had no faith; there was a time in which I could not believe in the Son of God for eternal life. 'But God, who is rich in mercy, for his great love wherewith he loved us, even when we were dead in sins [and unbelief; which is the greatest;] hath quickened us together with Christ, by grace ye are saved' (Eph 2:4,5), 'through faith' (v 8).
Exam. 7. Art thou born again? Then thou knowest that the doctrine of the Son of God, the Son of Mary, is a right doctrine, which is this:
That the Son of God which was with his Father before the world was (John 1:1, 17:5) came into the world in the fulness of time, and was made in the likeness of man (Phil 2:7) being made of a woman or virgin, made under the law, to redeem them that were under the law (Gal 4:4). And that was done in this wise. What the law could not do in that it was weak through the flesh; that is, through our flesh; God sending his own Son in likeness of sinful flesh, and for sin, condemned sin in the flesh, that is, condemned him in the flesh for the sins of poor sinners: For this, compare Romans 8:3; 2 Corinthians 5:21 with Galatians 3:13 and it will appear clearly to be the truth of God: Also, that this Son of God, which is the true God, as well as the Son of Mary, did bear our sins in his own body on the tree (1 Peter 2:24) and did spill his own blood, which is also the blood of God (Acts 20:28), that he died, and was laid in Joseph's sepulchre (John 19:38-42) and rose again the third day (Acts 10:40), that very Man (Luke 24:39-45), and ascended up into heaven in a cloud (Acts 1:9-11) and there ever lives to make intercession for us, that very man (Heb 7:24,25, 8:3, 10:12).
Exam. 8. And in the last place, If thou art a Christian, then thou lookest for that very Jesus again, whom the Jews did crucify (John 19), whom God raised again, as it is 1 Thessalonians 1:10. I say, thou lookest, thou waitest, thou hasteneth after the coming of this Lord Jesus, which doth deliver thee from the wrath to come (2 Peter 3:10-12; Heb 9:26-28; 1 Thess 1:10). Yea, thou knowest, that this very man shall so come in like manner, as his disciples did see him go into heaven, which was a very man (Luke 24:39 compared with vv 50,51 of the same chapter). Yea, in a cloud he went away from his disciples, and in the clouds he shall come again (Rev 1:7) to judge all that are in their graves (John 5:28,29; Dan 12:2) and shall receive all that look for, and love his second coming, to himself (Heb 9:27,28). And they shall be for ever with him (1 Thess 4:16,17). But the wicked shall be cast into eternal damnation (Matt 25:46). These things, I say, if thou be a Christian indeed, thou believest, and ownest, and the faith of them doth purify thy heart (1 John 3:3) and wean thee from this world, and the things thereof; and if it is not from this principle; that is, if thy obedience do not flow from this faith, which is the faith of God's elect, as I have proved at large, thy obedience, thy zeal, thy self-denial, thy holiness, righteousness; yea, all that thou canst do, is but sin in the sight of the great God of heaven and earth (Heb 11:6; Rom 14:23). For all true sanctification comes through the name of the Lord Jesus Christ, by the operation of the Spirit of God (1 Cor 6:11). 'But ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.' And (Cant 1:3), 'Thy name is as ointment poured forth, therefore do the virgins love thee.'
Well then, seeing this is a truth of so great concernment, I beseech you, seek to be thoroughly rooted into it by faith. And that thou mayest so be, examine thy heart; yea, beg of God to help thee to examine it, and to throw out all that fancy that thou takest instead of faith; also throw away all thine own wisdom; yea, thy own righteousness also, and come to God in the name of the Son of Mary, which is the Son of God, and beg faith of him, true faith, the faith of the operation of God; such a faith as he gives to his own elect, which will shew thee clearly of these things; so that thou shalt not deceive thyself with a fancy of them; and the advantages will be many.
Advantage 1. It will comfort thy heart against persecutions, temptations, and cross providences, as also James saith to his persecuted brethren; 'Be patient [my brethren, saith he], stablish your hearts, for the coming of the Lord draweth nigh' (John 5:8).
Advantage 2. It will through grace, wean thy heart and affections abundantly from this world, and the things therein. 'Who is he that overcometh the world, [saith John] but he that believeth that Jesus is the Son of God?' (1 John 5:5). Who is he also that purifies his heart, but he that looketh for the second coming of Christ from heaven to judge the world? as in 1 John 3:3 compared with 2 Peter 3:10, 11.
Advantage 3. Hereby thou wilt be able to judge of all doctrines whatsoever, though they come never so nigh the truth, yet if they be not indeed the very truth, thou wilt find them and their doctrine liars (Rev 2:2; 1 Cor 2:15).
Advantage 4. If thou beest thoroughly set down in this doctrine, even in the faith of this doctrine which I have held forth unto thee, thou wilt not be taken with any other doctrine whatsoever. What is the reason I pray you, that there are so many giddy-headed professors in these days, that do stagger to and fro like a company of drunkards, but this, They were never sealed in the doctrine of the Father, and the Son? They were never enabled to believe that that child that was born of the virgin Mary, was the mighty God (Isa 9:6). No, saith Christ, he that is built upon this rock, (meaning the faith of himself, which is to believe that the son of Mary is the Christ of God (Matt 16:16)) the gates of hell shall not prevail against him (v 18).
Advantage 5. The faith of this doctrine, will make thee labour in the work of God in the world. Oh, it will liven thy heart in the work of the Lord; especially, if thou livest in the faith of thy interest in Christ, it will make thee labour to be found watching when thy Lord shall return from the wedding; that when he doth come, thou mayest open to him immediately (Luke 12:35,36).
