The "Day of Calling" is a term that is not explicitly found in the Bible but is often used to describe the moment when God calls individuals to Himself, either for salvation, service, or a specific purpose. This concept is deeply rooted in the biblical narrative, where God calls people to enter into a relationship with Him, to fulfill His purposes, and to live according to His will.

Biblical Foundation

1. Calling to Salvation: The New Testament frequently speaks of God's call to salvation. In Romans 8:30, the Apostle Paul writes, "And those He predestined, He also called; those He called, He also justified; those He justified, He also glorified" . This passage highlights the divine initiative in the process of salvation, where God calls individuals to Himself, leading to justification and eventual glorification.

2. Calling to Service: Throughout the Bible, God calls individuals to specific tasks or roles. For example, in the Old Testament, God called Moses from the burning bush to lead the Israelites out of Egypt (Exodus 3:4). Similarly, in the New Testament, Jesus called His disciples to follow Him and become "fishers of men" (Matthew 4:19).

3. Calling to Holiness: Believers are also called to live a life of holiness and obedience. In 1 Peter 1:15-16, it is written, "But just as He who called you is holy, so be holy in all you do, for it is written: 'Be holy, because I am holy'" . This call to holiness is a fundamental aspect of the Christian life, reflecting God's character and purposes.

Theological Implications

The concept of the Day of Calling underscores the sovereignty of God in initiating a relationship with humanity. It emphasizes that God is the one who calls, and His call is effectual, meaning it accomplishes what He intends. This is seen in the doctrine of election, where God's call is part of His eternal plan for those He has chosen.

Moreover, the Day of Calling is a reminder of the personal nature of God's relationship with His people. It is not merely a general call to all humanity but a specific, personal invitation to each individual. This personal aspect is evident in passages like John 10:3, where Jesus says, "The sheep hear his voice; he calls his own sheep by name and leads them out" .

Practical Application

For believers, the Day of Calling is a call to respond in faith and obedience. It is an invitation to enter into a deeper relationship with God and to participate in His mission in the world. This involves discerning one's unique calling, whether it be in ministry, vocation, or daily life, and living it out with faithfulness and integrity.

The Day of Calling also serves as a source of assurance and encouragement. Knowing that God has called them, believers can have confidence in their identity and purpose in Christ. As Paul writes in Philippians 1:6, "being confident of this, that He who began a good work in you will carry it on to completion until the day of Christ Jesus" .

In summary, while the term "Day of Calling" may not be explicitly found in Scripture, the concept is deeply embedded in the biblical narrative, reflecting God's initiative in calling individuals to Himself for salvation, service, and holiness.
