The answer is: Corinthians

2 Cor 6:18

When Paul penned the words “I will receive you and will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty,” he was writing to the church in Corinth. It’s a profound sentiment illustrating the intimate relationship that believers are invited to have with the divine. Paul is emphasizing a covenantal connection, where God's role as a Father suggests care, protection, and unconditional love. This echoes other biblical texts, such as Isaiah 43:6, where God calls the people as His children, further reinforcing the themes of belonging and identity.

Here’s a fun trivia nugget: Corinth was a bustling city known for its diverse population, trade, and cultural vibrancy. However, it was also notorious for immorality, which explains much of Paul’s urging for purity and a higher standard of living among the church members. His heartfelt exhortations provide a genuine example of fatherly guidance trying to ensure their spiritual well-being amidst temptations.

Also worth noting is the term 'sons and daughters' used by Paul is groundbreaking, as it breaks societal norms of that era that often emphasized males over females. His inclusive language makes it clear that this relationship with the divine is open to all, regardless of social or gender status. Paul encourages unity and belonging, inviting every individual into a loving familial relationship with God, transcending earthly structures.
