What does the Bible say about being called sons of God?

Scripture explicitly states in 1 John 3:1, 'Behold what manner of love the Father hath bestowed upon us, that we should be called the sons of God.' This divine sonship is not based on human merit but on God's peculiar love and grace given to those He has chosen in Christ Jesus. Only through faith in His redemptive work can one be granted the privilege of being called a son or daughter of God. This affirmation underlines the uniqueness of God's love, which is bestowed upon His elect, contrasting with a general notion of all humanity being children of God.
