Since they are of Jacob’s lineage, who is also Israel, they became vessels of honor and were entrusted with the divine mission of proclaiming the gospel. Thus, He chose to exalt them with such glorious titles, having shone as lights in the world (Philippians 2:15) and bearing the word of the living God (Philippians 2:16), serving as hidden leaders for all those under the sun.
Therefore, He encourages, "Do not be afraid," meaning to be steadfast and strong, maintaining a patient and youthful spirit. Mock the rebellions of your adversaries and hold firm faith in God. Many will rise against the sacred message, and an unrighteous crowd will oppose your words; nonetheless, He instructs, rise above fear, laziness, and weakness, for I will provide water to those traversing this parched land. It is indeed a sweet and life-giving blessing for those longing souls to find springs of water. For those who walk in righteousness, it is even more desirable to be refreshed by divine and spiritual streams or comfort from the Spirit, which can revitalize a weary human spirit, granting renewed courage. The water promised by God to those in the barren land refers to the Holy Spirit. Indeed, our Savior said, “As the Scripture states, ‘The living waters shall flow from his belly,’” and the wise Evangelist clarified, “But this He spoke concerning the Spirit, whom those believing in Him were to receive” (John 7:38-39). Water gives life, nurtures the growth of trees and plants, and serves as a reflection of the Holy Spirit’s work, through whom all creation thrives and flourishes in every good thing and swiftly progresses toward spiritual maturity.
The assurance of water to those walking in a barren land signifies the life-giving influence and comfort of the Holy Spirit, as shown in the passage’s conclusion: “I will put My Spirit upon your descendants and My blessings upon your children.” By the descendants and children of the holy Apostles, we refer to those who are led to the knowledge of the truth and spiritual rebirth through their ministry, regenerating them not from perishable seed but through the word of the living and enduring God, alongside the work of the Holy Spirit. The Apostle Paul similarly states in his letter to those called through him, "Though you may have many teachers in Christ, yet you do not have many fathers; for in Christ Jesus, I have begotten you through the gospel" (1 Corinthians 4:15). Throughout his writings, he consistently refers to those who have come to believe in Christ through them as children. Therefore, I will place My Spirit upon your offspring and My blessings upon your children. The blessings from God to the saints encompass a variety of spiritual gifts: to one is given a word of wisdom, to another a word of knowledge, and so forth (1 Corinthians 12:8). Furthermore, Paul writes that each of us possesses a unique gift from God (1 Corinthians 7:7).
The blessings' purpose is revealed when He says, “They shall wither like grass by the water and like a willow tree by the flowing water.” Vegetation in dry areas grows sluggishly and quickly perishes, whereas those nourished by abundant streams thrive; the willow remains verdant due to its proximity to springs and rivers. Thus, those who are enriched with spiritual streams will acknowledge that they know Me alone; they will recognize Him who called them as God. The mention that one will say, "I am God," and another will cry out and write signifies the vast multitude who come to Him through faith in Christ. They shall not be identified by a single nation; rather, all the nations gathered shall declare that they belong to God, calling Him as their Savior and Redeemer, proclaiming their connection to Jacob as portions belonging to the Lord, His people, His heritage—Israel (Deuteronomy 32:9). We proudly assert that we are God's inheritance and part of Jesus Christ, our Savior.
