[Answ.] There is reason for it, and that both with respect to God and us.
1. With respect to God.
(1.) That it might be in a way of justice as well as mercy. And in a way of justice it could not have been, if it had not been by Christ; because he, and he only, was able to answer the demand of the law, and give for sin what the justice thereof required. All angels had been crushed down to hell for ever, had that curse been laid upon them for our sins, which was laid upon Jesus Christ; but it was laid upon him, and he bare it; and answered the penalty, and redeemed his people from under it, with that satisfaction to Divine justice that God himself doth now proclaim, That he is faithful and just to forgive us, if by faith we shall venture to Jesus, and trust to what he has done for life (Rom 3:24-26; John 1:4). (2.) Life must be by Jesus Christ, that God might be adored and magnified, for finding out this way. This is the Lord’s doings, that in all things he might be glorified through Jesus Christ our Lord. (3.) It must be by Jesus Christ, that life might be at God’s dispose, who hath great pity for the poor, the lowly, the meek, the broken in heart, and for them that others care not for (Psa 34:6; 138:6; 25; 51:17; 147:3). (4.) Life must be in Christ, to cut off boasting from the lips of men. This also is the apostle’s reason in Romans 3:19,27 (Eph 2:8-10).
2. Life must be in Jesus Christ with respect to us.
(1.) That we might have it upon the easiest terms, to wit, freely: as a gift, not as wages. Was it in Moses’ hand, we should come hardly at it. Was it in the pope’s hand, we should pay soundly for it. 20 But thanks be to God, it is in Christ, laid up in him, and by him to be communicated to sinners upon easy terms, even for receiving, accepting, and embracing with thanksgiving; as the Scriptures plainly declare (John 1:11,12; 2 Cor 11:4; Heb 11:13; Col 3:13-15). (2.) Life is in Christ FOR US, that it might not be upon so brittle a foundation, as indeed it would had it been anywhere else. The law itself is weak because of us, as to this. But Christ is a tried stone, a sure foundation, one that will not fail to bear thy burden, and to receive thy soul, coming sinner. (3.) Life is in Christ, that it might be sure to all the seed. Alas! the best of us, was life left in our hand, to be sure we should forfeit it, over, and over, and over; or, was it in any other hand, we should, by our often backslidings, so offend him, that at last he would shut up his bowels in everlasting displeasure against us. But now it is in Christ, it is with one that can pity, pray for, pardon, yea, multiply pardons; it is with one that can have compassion upon us, when we are out of the way; with one that hath an heart to fetch us again, when we are gone astray; with one that can pardon without upbraiding. Blessed be God, that life is in Christ! For now it is sure to all the seed. But,
Fourth, This doctrine of coming to Jesus Christ for life informs us of the evil of unbelief; that wicked thing that is the only or chief hindrance to the coming sinner. Doth the text say, “Come?” Doth it say, “and him that cometh to me I will in no wise cast out?” Then what an evil is that that keepeth sinners from coming to Jesus Christ! And that evil is unbelief: for by faith we come; by unbelief we keep away. Therefore it is said to be that by which a soul is said to depart from God; because it was that which at first caused the world to go off from him, and that also that keeps them from him to this day. And it doth it the more easily, because it doth it with a wile.
[Of the Sin of Unbelief.]—This sin may be called the white devil, for it oftentimes, in its mischievous doings in the soul, shows as if it was an angel of light: yea, it acteth like a counsellor of heaven. Therefore a little to discourse of this evil disease.
1. It is that sin, above all others, that hath some show of reason in its attempts. For it keeps the soul from Christ by pretending its present unfitness and unpreparedness; as want of more sense of sin, want of more repentance, want of more humility, want of a more broken heart.
2. It is the sin that most suiteth with the conscience: the conscience of the coming sinner tells him that he hath nothing good; that he stands inditeable for ten thousand talents; that he is a very ignorant, blind, and hard-hearted sinner, unworthy to be once taken notice of by Jesus Christ. And will you, says Unbelief, in such a case as you now are, presume to come to Jesus Christ?
3. It is the sin that most suiteth with our sense of feeling. The coming sinner feels the workings of sin, of all manner of sin and wretchedness in his flesh; he also feels the wrath and judgment of God due to sin, and ofttimes staggers under it. Now, says Unbelief, you may see you have no grace; for that which works in you is corruption. You may also perceive that God doth not love you, because the sense of his wrath abides upon you. Therefore, how can you bear the face to come to Jesus Christ?
