Final answer:
The right to become children of God, according to Christian theology, is given to those who believe in Jesus Christ and accept His sacrifice. This is an inclusive offer that transcends all boundaries, symbolizing the universal love of God for humanity.
Step-by-step explanation:
The question "Who did He (true Light) gave the right to become children of God?" is rooted in Christian theology, which posits that through belief in Jesus Christ and acceptance of His sacrifice, individuals are given the right to become children of God. This notion is central to Christian beliefs, wherein the acceptance of Jesus Christ as one's savior is viewed as the pathway to spiritual adoption into God's family. The New Testament of the Bible, especially the Gospel of John, emphasizes this concept by stating that those who receive Jesus and believe in His name are given the right to become children of God.
In multiple references throughout these texts, the message is clear: God's forgiveness is available to all, and the path to becoming a child of God is open to every human being, regardless of their background or past. This includes the idea that Jesus died for all humanity, providing a way for eternal life and reconciliation with God for everyone who believes. The inclusivity of this offer extends beyond any racial, cultural, or social boundaries, affirming the universal love of God for all his creation.
