Why is being a son of God important for Christians?

The importance of being a son of God for Christians lies in the profound shift in identity and relationship. According to 1 John 3:1-2, believers are not only saved from sin but are also brought into a familial relationship with God. This new identity impacts their relationship with the world and each other, as they are now part of a divine family. Furthermore, this adoption encourages holiness and a transformation of character, aiming to make believers conform to the image of Christ, as evidenced in John 2:3-5, which states that those who are truly in Christ will keep His commandments.
