With the arrival of Jesus Christ, the prophetic voice was to be silenced, as it had completed its mission and had communicated God’s will in due time. Thus, the expectation for the kingdom was fulfilled, and the pursuit to enter it commenced. However, mere negation of sinful actions—such as not murdering, stealing, committing adultery, or bearing false witness—is insufficient for entrance into the Kingdom of Heaven. Instead, positive virtues are required, such as self-sacrificial love even toward one’s enemies and charity toward all. This necessitates not only the avoidance of sin but also the active performance of good deeds for the benefit of others. Achieving this entails effort and struggle against personal desires and temptations, making entry into this kingdom more challenging than the Jews imagined. Though the kingdom of heaven drew near with John's arrival and was made evident with Christ's coming, it is only those who strive to achieve the perfection He outlined—who earnestly endeavor to take the kingdom by force—who will enter. This endeavor is central to the Lord's teaching on salvation. Unfortunately, many, including various Protestant sects and some Orthodox Christians, overlook this truth.
Some Orthodox Christians express complete distrust in human agency, asserting that individuals cannot contribute to their salvation. They cite the Lord’s words, “without Me you can do nothing.” However, this interpretation stems from a misunderstanding of Christ’s analogy, where He compares Himself to a vine and His followers to its branches. He stated, "I am the vine, and My Father is the Vinedresser... and ye are the branches." Just as a branch cannot bear fruit by itself unless it is connected to the vine, so Christ’s followers can only yield spiritual fruit if they live in unity with Him, drawing sustenance from the same spiritual nourishment that empowered Him through submission to the Father’s will. Christ not only instructed us on obeying God's will but also exemplified this obedience in His life, serving as our model. Without striving to emulate Him and following His life example, we truly cannot achieve salvation. Imitating Christ means adhering to all His commandments, demanding human effort to overcome personal weaknesses and resist temptations.
Therefore, the Lord’s teachings do not justify dismissing our own strength. Certainly, human capacity is limited; we cannot achieve salvation without divine aid and God’s gracious mercy. Just as a vine branch may suffer from pests or disease that it cannot manage alone, requiring the vinedresser’s intervention, so too do we need the assistance of our heavenly Vinedresser in our battle against temptations. When we seek His help, it is granted, for the Lord assured us, “Ask, and it will be given to you.” Yet, it becomes clear that without following Christ’s example and effort toward sanctification in conjunction with His grace, salvation remains unattainable.
Consequently, it is a grave error for Orthodox Christians to exhibit doubt in human agency, expecting salvation solely through divine mercy. They overlook a crucial principle of Christ’s teaching—that the Kingdom of Heaven is taken by those who earnestly strive for it. It is not acquired through physical force as earthly kingdoms are, but its gates open only for those who work diligently to render themselves worthy of it. Conversely, those who rely solely on their faith without striving for self-improvement will find the gates barred, and they will face the Lord’s words: "Truly, I say to you, I do not know you! Depart from Me!" This message is direct and unambiguous, repeated frequently by Christ. He illustrated it through parables, stating, “Wide is the gate, and broad is the way that leads to destruction, and many enter through it; but narrow is the gate and difficult is the way that leads to life, and few find it.”
Further confirming this truth, the Lord implored, “Strive to enter through the narrow gate; for many, I tell you, will seek to enter and will not be able.” Many will desire to enter too late; they will knock and plead for the door to be opened, citing their faith, their understanding of His sacrificial work, and familiarity with His teachings. Yet, all these pleas will be in vain; they have failed to put forth the effort required to be worthy of the Kingdom of Heaven. Thus, the gates will remain closed, and they will hear the verdict: "Depart from Me, all you workers of iniquity." In the parable of the ten virgins awaiting the bridegroom, the Lord referred to such carelessness as foolishness, declaring they would hear the same judgment: "Get away! I don't know you." Similarly, in the parable of the talents, Christ explained that those who do not utilize even their smallest gifts—strength endowed to them for striving toward the kingdom—will find the gates closed to them, regardless of their belief in Him as Lord, because they buried their talents rather than using them to unlock the kingdom.
All these teachings from the Lord affirm that the Kingdom of Heaven is indeed seized by those who actively combat their passions, investing considerable effort in their spiritual struggle to emerge victorious. The Kingdom of Heaven awaits those who diligently cultivate and exercise their spiritual strength as directed by Christ. A person who has honed his willpower through struggles and emerged victorious gains an ability to master his desires, rendering the temptations ineffective; the tempter avoids such an individual, having been rendered unfit for sin. Nevertheless, despite all such efforts, divine assistance remains essential; without it, one cannot even draw near to the Kingdom’s gates. Entrance is ultimately facilitated by our Lord Jesus Christ, who bore the sins of those seeking Him through His redemptive sacrifice. Thus, while the Kingdom of Heaven is pursued with earnest effort, this pursuit cannot be divorced from the necessity of God's help.
