The One Who Is, Who Was, and Who Is to Come

The One Who Is, Who Was, and Who Is to Come

A Pastoral Sermon Reflecting on Revelation 1:8

Revelation 1:8 records a declaration that echoes across all of history and beyond it: “I am the Alpha and the Omega,” says the Lord God, “who is, and who was, and who is to come, the Almighty.” These words stand at the opening of the final book of Scripture like a great doorway into the mystery of God’s eternal reign. They are not merely poetic language or symbolic imagery. They are a proclamation about the nature of God, the direction of history, and the hope of every believer.

The statement “I am the Alpha and the Omega” uses the first and last letters of the Greek alphabet to describe the completeness of God’s being. Just as Alpha begins the alphabet and Omega concludes it, God encompasses the beginning and the end of all things. Nothing exists outside of His authority, His knowledge, or His presence. Before the first moment of creation unfolded, God was already present. After the last chapter of human history closes, God will still be enthroned. Everything that exists lives and moves within the reality of His eternal existence.

This truth confronts the tendency to view life as fragmented or random. The world often appears chaotic, uncertain, and unpredictable. Events unfold in ways that seem disconnected from any meaningful purpose. Yet Revelation reminds the church that history is not wandering aimlessly. It begins with God, it unfolds under His sovereignty, and it will ultimately conclude in His victory. The Alpha who initiated creation is the same Omega who will bring it to completion.

When God declares Himself to be the Alpha and the Omega, He is also revealing His authority over time itself. Human beings experience time as a series of moments that pass quickly and irreversibly. Yesterday cannot be revisited, tomorrow cannot be fully known, and today often feels fragile and fleeting. God, however, is not confined by this sequence. He is the One “who is, and who was, and who is to come.” These three dimensions of time describe the eternal presence of God rather than three separate stages of His existence.

“Who is” affirms that God is present right now. The Lord is not a distant deity who created the universe and then withdrew from it. He is actively present in the life of the world and in the lives of His people. Every breath, every heartbeat, every sunrise testifies that creation continues to exist because God sustains it. The God who revealed Himself to Moses as “I AM” remains the ever-present One who upholds all things.

“Who was” points to God’s faithfulness in the past. The story of Scripture is filled with moments where God acted to redeem, rescue, and guide His people. From the calling of Abraham to the deliverance of Israel from Egypt, from the giving of the law to the promises spoken by the prophets, the past reveals a consistent pattern of divine faithfulness. The God who was present then has not changed. His character remains constant, His promises remain reliable, and His purposes remain sure.

“Who is to come” points toward the future fulfillment of God’s kingdom. Revelation was written to believers who were facing persecution, uncertainty, and suffering. They lived in a world where the powers of the empire seemed overwhelming and where faithfulness to Christ often brought hardship. Into that situation came the assurance that God is not only the God of the past and the present, but also the God who is coming. History is moving toward a moment when the fullness of His reign will be revealed.

The phrase “the Almighty” reinforces this promise. The Greek word translated as Almighty speaks of absolute power and unmatched authority. It means that God possesses the ability to accomplish everything He intends. No earthly ruler, no spiritual force, no human rebellion can overturn the will of the Almighty. What God has promised will come to pass because His power is limitless.

These truths shape the way believers understand their lives and the world around them. To confess that God is the Alpha and the Omega means recognizing that life begins with Him. Humanity did not create itself, nor does it define its own ultimate purpose. Every life is a gift that originates from the creative will of God. Because He is the beginning, true meaning cannot be discovered apart from Him.

Modern culture often encourages people to define themselves according to personal ambition, social expectations, or material success. Yet these foundations are fragile. Careers change, reputations fade, wealth disappears, and achievements eventually pass into memory. When identity is built on these shifting foundations, life becomes unstable. Revelation calls believers to ground their identity in the eternal God who stands at the beginning of all things.

To believe that God is the Omega means trusting Him with the end as well. Many fears arise from uncertainty about the future. Questions about what will happen tomorrow, next year, or at the end of life can create anxiety and restlessness. Yet the declaration of Revelation assures believers that the end of the story belongs to God. The same Lord who began creation will bring it to its rightful completion.

This perspective changes the way suffering is understood. Trials and hardships often feel overwhelming because they appear to define the whole story. When pain is viewed as the final chapter, despair becomes understandable. But Revelation insists that suffering is never the final word. The Omega still waits ahead, and the Omega is the victorious God who will set all things right.

The church throughout history has drawn strength from this promise during seasons of persecution and uncertainty. Believers facing imprisonment, exile, or martyrdom have clung to the assurance that the Almighty governs the future. Empires rise and fall, ideologies come and go, and cultures change with time, but the kingdom of God endures beyond them all.

This truth also invites humility. If God is the Alpha and the Omega, then human beings are neither the beginning nor the end of the story. The world does not revolve around human desires or ambitions. Instead, humanity exists within the larger narrative of God’s purposes. Recognizing this reality leads to worship, gratitude, and reverence.

Worship naturally arises when believers contemplate the eternal nature of God. The One who transcends time, who holds the past, present, and future in His hands, deserves awe and devotion. Worship becomes more than a weekly practice; it becomes the response of a heart that recognizes the majesty of the Almighty.

Gratitude flows from the realization that this eternal God has chosen to reveal Himself to humanity. The God who existed before the universe spoke the world into being and then entered human history through Jesus Christ. The Alpha who began creation stepped into creation in order to redeem it. The Omega who will complete history has already secured victory through the death and resurrection of Christ.

Reverence grows when believers remember that the Almighty is not merely powerful but also holy. The God who governs the universe calls His people to live in a way that reflects His character. To belong to the Alpha and the Omega means living lives shaped by His truth, guided by His Spirit, and committed to His kingdom.

Practically, this means that everyday decisions are not isolated from the larger story of God’s purposes. Choices about integrity, compassion, generosity, and faithfulness all reflect whether life is oriented toward the eternal God or toward temporary concerns. When believers remember that God is the beginning and the end, priorities begin to shift. Eternal values rise above immediate gratification.

Hope also grows from this vision of God’s sovereignty. In a world filled with uncertainty, believers are not left to navigate life alone. The One who stands at the beginning and the end walks with His people through every moment in between. His presence provides guidance when the path is unclear, strength when the burden feels heavy, and peace when circumstances seem overwhelming.

The message of Revelation 1:8 therefore speaks with enduring relevance. It reminds the church that the foundation of faith is not found in human strength or worldly stability but in the eternal character of God. He is the Alpha who began the story, the Omega who will complete it, the One who is present now, the One who has always been faithful, and the One who will come again in power and glory.

To live in light of this truth is to walk with confidence, humility, and hope. Confidence arises because the Almighty holds the future. Humility grows because life belongs to Him. Hope endures because the story of the world is moving toward the fulfillment of His promises.

In every generation the church returns to this declaration as a source of strength: the Lord God is the Alpha and the Omega, the One who is, who was, and who is to come, the Almighty. History rests in His hands, the present unfolds under His watchful care, and the future moves steadily toward the moment when His kingdom will be fully revealed. And in that assurance the people of God continue to live, worship, and hope.
