Why does God refer to Christians as His children?

In John 13:33, Jesus calls His followers "my little children," which signifies a deep familial bond between God and His people. This relationship is made possible through the work of regeneration, where believers are spiritually birthed into God's family. Moreover, this adoption is not based on human merit but on the sovereign grace of God, affirming that all believers are granted the status of children of God. This term underscores the intimate and personal relationship believers have with their Creator, assuring them of His love, care, and nurturing as they walk in faith.
