The term "follow-up" does not explicitly appear in the Bible, but the concept of following up can be understood through various biblical principles related to discipleship, accountability, and pastoral care. In the New Testament, Jesus emphasized the importance of discipleship and nurturing relationships among believers. For example, in Matthew 28:19-20, known as the Great Commission, Jesus instructs His followers to "go therefore and make disciples of all nations, baptizing them... teaching them to observe all that I have commanded you." This directive implies an ongoing relationship where new believers are nurtured and guided, embodying the essence of follow-up.Additionally, the Apostle Paul exemplified follow-up in his ministry. After establishing churches, he often revisited them or sent letters to provide encouragement, correction, and instruction (e.g., 1 Thessalonians 3:1-2). This practice underscores the importance of maintaining relationships and ensuring spiritual growth, which aligns with the modern understanding of follow-up in a church or ministry context. Thus, while the term may not be present, the biblical principles of nurturing, guiding, and holding one another accountable resonate with the idea of follow-up in the Christian faith.
