10. If you keep my commandments. He points out to us the method of perseverance. his, to follow where he calls, for, as Paul says,

They who are in Christ walk not according to the flesh, but according to the Spirit,
(Romans 8:1.)

For these two things are continually united, that faith which perceives the undeserved love of Christ toward us, and a good conscience and newness of life. And, indeed, Christ does not reconcile believers to the Father, that they may indulge in wickedness without reserve, and without punishment; but that, governing them by his Spirit, he may keep them under the authority and dominion of his Father. Hence it follows, that the love of Christ is rejected by those who do not prove, by true obedience, that they are his disciples.

If any one object that, in that case, the security of our salvation depends on ourselves, I reply, it is wrong to give such a meaning to Christ’s words; for the obedience which believers render to him is not the cause why he continues his love toward us, but is rather the effect of his love. For whence comes it that they answer to their calling, but because they are led by the Spirit of adoption of free grace?

But again, it may be thought that the condition imposed on us is too difficult, that we should keep the commandments of Christ, which contain the absolute perfection of righteousness, — a perfection which far exceeds our capacity, — for hence it follows, that the love of Christ will be useless, if we be not endued with angelical purity. The answer is easy; for when Christ speaks of the desire of living a good and holy life, he does not exclude what is the chief article in his doctrine, namely, that which alludes to righteousness being freely imputed, in consequence of which, through a free pardon, our duties are acceptable to God, which in themselves deserved to be rejected as imperfect and unholy. Believers, therefore, are reckoned as keeping the commandments of Christ when they apply their earnest attention to them, though they be far distant from the object at which they aim; for they are delivered from that rigorous sentence of the law,

Cursed be he that hath not confirmed all the words of this law to do them,
(Deuteronomy 27:26).

As I also have kept my Father’s commandments. As we have been elected in Christ, so in him the image of our calling is exhibited to us in a lively manner; and therefore he justly holds himself out to us as a pattern, to the imitation of which all the godly ought to be conformed. “In me,” says he, “is brightly displayed the resemblance of those things which I demand from you; for you see how sincerely I am devoted to obedience to my Father, and how I persevere in this course. My Father, too, hath loved me, not for a moment, or for a short time, but his love toward me is constant.” This conformity between the Head and the members ought to be always placed before our eyes, not only that believers may form themselves after the example of Christ, but that, they may entertain a confident hope that his Spirit will every day form them anew to be better and better, that they may walk to the end in newness of life.

11. These things I have spoken to you. He adds, that his love is far from being unknown to the godly, but that it is perceived by faith, so that they enjoy blessed peace of conscience; for the joy which he mentions springs from that peace with God which is possessed by all that have been justified by free grace. As often, then, as God’s fatherly love towards us is preached, let us know that there is given to us ground for true joy, that, with peaceable consciences, we may be certain of our salvation.

My joy and your joy. It is called Christ’s joy and our joy in various respects. It is Christ’s, because it is given to us by him; for he is both the Author and the Cause of it. I say that he is the Cause of it, because we were freed from guilt, when

the chastisement of our peace was laid on him, (Isaiah 53:5.)

I call him also the Author of it, because by his Spirit he drives away dread and anxiety in our hearts, and then arises that calm cheerfulness. It is said to be ours for a different reason; because we enjoy it since it has been given to us. Now since Christ declares that he spake these things, that the disciples might have joy, we conclude from these words, that all who have duly profited by this sermon have something on which they can rest.

That my joy may abide in you. By the word abide he means, that it is not a fleeting or temporary joy of which he speaks, but a joy which never fails or passes away. Let us therefore learn that we ought to seek in the doctrine of Christ the assurance of salvation, which retains its vigor both in life and in death.

That your joy may be full. He adds, that this joy will be solid and full; not that believers will be entirely free from all sadness, but that the ground for joy will be far greater, so that no dread, no anxiety, no grief, will swallow them up; for those to whom it has been given to glory in Christ will not be prevented, either by life, or by death, or by any distresses, from bidding defiance to sadness.

12. This is my commandment. Since it is proper that we regulate our life according to the commandment of Christ, it is necessary, first of all, that we should understand what it is that he wills or commands He now therefore repeats what he had formerly said, that it is his will, above all things, that believers should cherish mutual love among themselves. True, the love and reverence for God comes first in order, but as the true proof of it is love toward our neighbors, he dwells chiefly on this point. Besides, as he formerly held himself out for a pattern in maintaining the general doctrine, so he now holds himself out for a pattern in a particular instance; for he loved all his people, that they may love each other. Of the reason why he lays down no express rule, in this passage, about loving unbelievers, we have spoken under the former chapter.

13. Greater love hath no one than this. Christ sometimes proclaims the greatness of his love to us, that he may more fully confirm our confidence in our salvation; but now he proceeds further, in order to inflame us, by his example, to love the brethren. Yet he joins both together; for he means that we should taste by faith how inestimably delightful his goodness is, and next he allures us, in this way, to cultivate brotherly love. Thus Paul writes:

Walk in love, as Christ also hath loved us, and hath given himself for us an offering and sacrifice to God of a sweet-smelling savor, (Ephesians 5:2.)

God might have redeemed us by a single word, or by a mere act of his will, if he had not thought it better to do otherwise for our own benefit, that, by not sparing his own well-beloved Son, he might testify in his person how much he cares for our salvation. But now our hearts, if they are not softened by the inestimable sweetness of Divine love, must be harder than stone or iron.

But a question is put. How did Christ die for friends, since

we were enemies, before he reconciled us, (Romans 5:10;)

for, by expiating our sins through the sacrifice of his death, he destroyed the enmity that was between God and us? The answer to this question will be found under the third chapter, where we said that, in reference to us, there is a state of variance between us and God, till our sins are blotted out by the death of Christ; but that the cause of this grace, which has been manifested in Christ, was the ⁸⁴⁸⁴     See volume 1. In this way, too, Christ laid down his life for those who were strangers, but whom, even while they were strangers, he loved, otherwise he would not have died for them.

14. You are my friends. He does not mean that we obtain so great an honor by our own merit, but only reminds them of the condition on which he receives us into favor, and deigns to reckon us among his friends; as he said a little before,

If you keep my commandments, you will abide in my love,
(John 15:10.)

For the grace of God our Savior hath appeared, teaching us that, denying ungodliness and worldly desires, we should live soberly, and righteously, and piously, in this world,
(Titus 2:11.)

But ungodly men, who, through wicked contempt of the Gospel, want only oppose Christ, renounce his friendship.
