Topical Lexicon
Overview

Strong’s Greek 839, αὔριον, designates “tomorrow” or “the next day.” In the New Testament it regularly draws a contrast between present obedience and presumptive planning. Whether spoken by Christ, an apostle, or an inspired writer, the term underscores human frailty, divine sovereignty over time, and the urgency of holy living.

Literary usage in the Gospels

Matthew 6:30–34 anchors Jesus’ teaching on anxiety: “Therefore do not worry about tomorrow, for tomorrow will worry about itself” (Matthew 6:34). The repetition of αὔριον frames “today” as the arena of faith and lifts worry out of the disciple’s hands.

Luke develops the motif further. In Luke 12:28 αὔριον is used of grass “here today and tomorrow…thrown into the furnace,” stressing life’s brevity. Luke 13:32–33 shows Jesus firmly on mission: He will work “today and tomorrow,” then finish on the third day, an allusion to His impending passion that sets divine timetable above Herod’s threats. In the parable of the Good Samaritan, αὔριον (Luke 10:35) introduces planned generosity, highlighting that godly care for others rightly projects into the future without presumption.

Usage in Acts

The narrative portions of Acts employ αὔριον to record judicial schedules (Acts 4:3, 4:5), conspiratorial plots (Acts 23:20), and governmental hearings (Acts 25:22). Luke thus shows that the gospel’s advance intersects human calendars yet is never constrained by them; every “tomorrow” in Acts unfolds under God’s providence, often surprising rulers who think they control events.

Pauline usage

In 1 Corinthians 15:32 Paul quotes the nihilistic proverb, “Let us eat and drink, for tomorrow we die”, using αὔριον to expose the void left when resurrection hope is denied. The apostle’s argument flips the worldly maxim: because tomorrow is secured by Christ’s victory, indulgent fatalism loses its attraction and sacrificial service now makes eternal sense.

Pastoral application in James

James 4:13–14 rebukes merchants whose confident itineraries presume upon αὔριον: “You do not even know what tomorrow will bring”. Here the word functions pastorally, leading believers to submit plans with a humble “If the Lord wills.” The passage balances responsible foresight with wholehearted dependence on God’s inscrutable purposes.

Theological significance

1. Human limitation: Every occurrence of αὔριον reminds readers that life is “a vapor that appears for a little while and then vanishes” (James 4:14).
2. Divine sovereignty: God alone commands “tomorrow,” whether in providing (Matthew 6), judging (Acts 4), or glorifying His Son (Luke 13).
3. Eschatological urgency: The kingdom agenda is pressing; today is the day of response, repentance, and righteous action.
4. Ethical orientation: Plans are commended when they express faith (Luke 10:35) and cautioned when they express self-reliance (James 4:13).

Historical context

In first-century Jewish reckoning, the day began at sundown, so “tomorrow” could commence within hours. Roman legal and administrative life also operated on tightly ordered “next-day” proceedings, as reflected in Acts. Understanding this background heightens appreciation for the immediacy felt by Jesus’ listeners and the early church when confronted with αὔριον.

Contemporary ministry implications

• Preaching: Use αὔριον texts to call hearers from procrastination to prompt obedience.
• Pastoral care: Encourage dependance on God for future provision while discouraging anxiety.
• Mission strategy: Plan diligently yet hold schedules loosely, acknowledging that divine openings or closures may shift any “tomorrow.”

By tracing αὔριον across Scripture, one finds a consistent summons: live faithfully today, trust God for tomorrow, and rest in the assurance that every future moment belongs to Him who “is the same yesterday and today and forever.”
