NOTES for Mat 7:21-29
The Sermon on the Mount ends with an important observation from the Savior: for the Kingdom, what matters most is relationships, relationships with Him and with neighbors. Otherwise a person's whole life is like a house built on sand. At first glance, a person who in Christ's name not only prophesied, but even cast out demons and worked miracles, must be a disciple of Christ, and if so, his path must certainly end in the Kingdom. In reality, however, everything turns out not to be so simple.
The main problem here is that fallen man in general tends to substitute form for content. In this case, paradoxical as it may sound, the form turns out to be precisely prophecies, the casting out of demons, and even miracles - everything we tend to regard as content, treating only the religious shell of a spiritual tradition as form.
If we were not talking about Christianity, that would indeed be so. But Christianity is unique. It is not a new religion, not a new theology, not a new morality, and not even a new spiritual tradition; it is a new life. And in life, the main thing is life itself. Its flow. Its process. Its spiritual quality, its very dynamic - the very thing a modern philosopher would call existence. And, of course, relationships - with God, with Christ, with other people.
After all, relationships determine the structure of our life, its spiritual algorithm. Christianity is not about what to do, but about how to be, how to live, in what spiritual state to exist. This is the content of Christianity - and all external activity here is nothing other than form.
Meanwhile, among Christians in every age there has been a strong temptation toward a kind of religious activism, when Christianity itself began to be perceived as a practice - not the practice of life itself, but of specific activities and "spiritual" works. Religious education, charity, missionary work - the list can be continued, if not indefinitely, then for a very long time. It is taken for granted that the more such works a person completes in a unit of time, the more active he is in this respect, the better a Christian he is.
It is no wonder that many have tried, and still try, with all their strength - even to the point of a mental or nervous breakdown, which they often regard as a cross connected with the "ministry" that "God has supposedly entrusted" to them. Such people often do not even realize that God wants something entirely different from them, just as they do not realize that their breakdowns, crises, and at times more serious problems are precisely the collapse of the house built on sand that Jesus speaks about.
