Introduction

This pivotal verse marks a crucial moment in the history of Israel as they prepare to cross the Jordan River into the Promised Land. The call to sanctification serves both as a physical and spiritual preparation for the wonders that God is about to reveal. This commentary will explore the theological implications, practical applications, and historical context of this command.

The Call to Sanctification

The command given by Joshua to "Sanctify yourselves" stresses the need for purification and readiness in the life of the people. This theme of sanctification permeates the scriptures and serves several important functions:

• Preparation for Divine Encounter: The act of sanctification signifies preparing one’s heart and mind to meet with God. Matthew Henry emphasizes that personal holiness is essential when approaching God's significant acts.
• Collective Responsibility: Joshua addresses the entire nation, indicating that sanctification is not merely an individual act but a communal one. Albert Barnes reflects on how Israel’s collective purity affects their standing before God.
• Anticipation of God's Wonders: By sanctifying themselves, the people of Israel express their expectation of God’s movement among them. Adam Clarke highlights the linkage between holiness and the reception of divine miracles.

The Significance of "Tomorrow"

The word "tomorrow" signifies imminent action. It indicates a time of opportunity and divine intervention. This notion is explored in various commentaries:

• Expectation of the Miraculous: Emphasizing anticipation, Matthew Henry remarks that God’s wonders often come when His people are ready to meet Him in faith and obedience.
• Urgency of Preparation: The immediacy of tomorrow implies that there is little time for delay in preparing oneself spiritually. The urgency in Joshua's words serves as a reminder to believers today about the importance of spiritual readiness.

The Nature of God's Wonders

The wonders that God promises to perform are not merely miraculous acts; they encompass His broader plan for Israel and humanity:

• Historical Context: The crossing of the Jordan River was a foundational act in Israel’s history, symbolizing the transition from wilderness wandering to inheriting the land promised to Abraham, Isaac, and Jacob. Barnes illustrates how these wonders affirm God's covenant faithfulness.
• Spiritual Significance: The wonders performed were tangible manifestations of God’s glory and power. Clarke notes how in spiritual terms, God’s wonders lead to deeper faith and a clearer understanding of His character.
• Continued Relevance: The expectation of God's wonders continues today. The modern church is called to sanctification in anticipation of the Holy Spirit’s work. Henry’s remarks draw parallels between Israel’s experience and today’s Christian journey.

Application for Today

The principles derived from Joshua 3:5 have profound implications for contemporary believers:

• Personal Reflection: Just as the Israelites were called to sanctify themselves, believers today are called to examine their hearts and lives for areas of sin and disobedience. This process is foundational for experiencing God’s transformative power.
• Community of Faith: The call to sanctification is communal. Churches should encourage collective holiness and accountability among members to prepare for God’s work among them.
• Expectation and Faith: Like the Israelites, believers should live in expectation of God’s intervening power. Faith in God's promises while engaging in acts of sanctification signifies trust in His character and desires.

Theological Implications

This passage also invites theological reflection regarding the sanctifying work of the Holy Spirit:

• Holiness in the New Covenant: Under the new covenant, sanctification comes through faith in Jesus Christ. The call to sanctify oneself resonates with the New Testament calls to holiness (1 Peter 1:16, 2 Corinthians 7:1).
• God's Ongoing Work: Just as God worked wonders among the Israelites, He continues to equip believers today through the Holy Spirit to fulfill His mission on earth. Thus, the anticipation of God's wonders is as relevant now as it was then.

Conclusion

Joshua 3:5 encapsulates a call to holiness, preparation, and expectation of divine wonders. As pastors, students, theologians, and scholars engage with this text, it invites deep reflection on the nature of God’s holiness, the importance of readiness, and the anticipation of God’s mighty works in our lives today. The path to experiencing God’s power remains through our commitment to holiness—a message as vital now as it was for the Israelites at the Jordan River.
