When speaking to His disciples about the Kingdom, Jesus constantly calls them to love one another (vv. 9-12, 17). This is unsurprising if we recall that Christianity is nothing other than life in the Kingdom, and therefore life in love. Love, of course, is not the Kingdom's only characteristic. The life of the Kingdom is also the breath of God that permeates it and those manifestations of God's power that accompany Jesus everywhere during His earthly ministry. Yet in our still not fully transformed world, the love characteristic of those who bear the Kingdom seems to be its clearest testimony.

Power, for example, is well known to the untransformed world. Indeed, in a world lying in evil there is sometimes even too much of it. Power can sometimes make people submit, but it cannot make them love. Relationships imposed by force, and therefore involuntary, are unsuitable for the Kingdom. Power in the fallen world will hardly be perceived as an alternative to the existing order. The same could be said of spiritual phenomena in themselves, for the fallen world too knows a peculiar kind of spirituality. The spiritual phenomena characteristic of fallen nature differ qualitatively in essence from the spiritual influences that proceed from the Kingdom, of course, but outwardly they can sometimes look alike, and to someone who sees only the outward appearance the difference may be imperceptible. Thus spirituality in itself does not necessarily mean that an alternative to the laws of this world has appeared.

For such an alternative to appear, everyone must be able not only to see clearly that Christ's disciples and followers possess a certain spirituality, but also to discern what it is. In this respect the witness of the love permeating every relationship in the Kingdom is the best, because mutual love visibly demonstrates to the world precisely what it does not have and what it lacks so greatly. Unlike power and spirituality as such, love can therefore become the alternative to the existing world order that the world both longs for and fears. It fears this alternative because, from the standpoint of the laws of our still untransformed world, relationships of love really are contrary to nature. Both nature and society, which has not moved so very far beyond it, follow different principles, relying on power, advantage, and efficiency.

It is no surprise that those who want to live differently in this world become a foreign body within it (vv. 18-19). But some are prepared at least to try to find an alternative, and so those who live by the laws of the Kingdom will face not only persecution. There will also be people ready to listen to their testimony and follow their path (v. 20). Nevertheless, Christ's disciples and followers should apparently neither try to escape persecution nor hope for their preaching to achieve mass success, for, in Jesus' words, “the servant is not greater than his lord.” Only the testimony is fundamentally important. Everyone decides for himself how to respond to it.

Jesus builds His conversation with the disciples on a contrast: I give you a commandment to love one another because the world hates you. In the world there is hatred; among you there is love.

Two questions immediately arise here. First, can the disciples' love overpower the world's hatred, if the world is always larger and the disciples themselves do not really know how to love? And second, it is clear that the situation is not so polarized at all: in the world that does not believe in Christ, love is always present (for people cannot live entirely without love), and among Christians love, to put it mildly, is not the most frequent guest either.

As for the first question, one can only note that the matter is not the disciples' own love, but the mercy of the Father; and who is stronger - God or the world's evil - is a question addressed to the very depth of our being, since it has no "external" answer. As for polarization, the matter is apparently not a division into "believers and unbelievers" (it is unclear how to divide them), but the opposition between Christ and "the world" within each person again.

Speaking of love as a new commandment, Jesus first of all requires every Christian to be ready to “lay down his life for his friends.” Usually this is understood as readiness to give up one’s life for friends. Yet the corresponding Greek verb means not “give up,” but precisely “lay down,” “place” — and not “instead of,” but precisely “for the sake of,” “on behalf of” friends. Obviously, this is not about self-sacrifice, or at least not only about it; rather, we should speak of the relationships that bind together people who live by the love with which Jesus loved each person. But what is this love of His, the love of the Kingdom? How does it differ from the love that people knew long before His coming into the world?

First of all, in this: human love has never been complete. It remained only an intention, a relationship, and in this sense it was a spiritual reality. But the environment within which relationships of love existed was natural, psychic: in the fallen state, after all, the human being remained primarily a natural being, and the psyche too is nature, only of a special kind.

Jesus, however, speaks of the love of the Kingdom, that Kingdom where the very environment of communion is not natural but spiritual. There love can be manifested in absolute fullness: in the Kingdom, the relationships and the environment fully correspond to one another. But a person’s life in the Kingdom cannot belong to that person alone.

Jesus Himself explains this simply: whoever wants to keep his life for himself loses it, but whoever gives it to Him and makes it part of the life of His Kingdom preserves it. And preserves it in a fullness that cannot be found in the fallen world. But if this is true of the life of the Kingdom as a whole, it is just as true when the matter concerns the relationship of the inhabitants of the Kingdom to one another: they too never belong only to themselves; their life never is and never can be something isolated, as the life of a person in the untransfigured world can be.

Of course, in the Kingdom too each person lives his own life, not someone else’s. But if the boundaries of this life in the fallen world are often closed to any interaction, in the Kingdom they are always open. There this is safe: since the life of each person is determined by God’s breath, no one abuses this openness as sometimes happens in the fallen world.

And with such openness the possibilities become immense: if necessary, each person can at any moment even completely yield his own living space to another, should the need arise. No unsolvable tasks remain for the inhabitants of the Kingdom, for there are no barriers between them either. And therefore there are no barriers for God’s breath, which unites them. Each person lives a full life, belonging at the same time both to himself and to everyone who wants to share in that fullness and take part in it.

This is the kind of life the Savior commands His disciples to live. In essence, it is Christianity itself.
