Final answer:
The correct answer is option 4. John is emphasizing that Jesus is known as the Son of God in Christian doctrine, who came to offer spiritual salvation rather than a political revolution.
Step-by-step explanation:
John's concern that we understand God and that Jesus is the Son of God aligns with the faith's central doctrines. Christianity teaches that Jesus Christ is the savior who brings spiritual liberation rather than political revolution. This salvation centers on the belief that Jesus, through his sacrifice on the cross, opened the way for humanity to gain eternal life in heaven. The title 'Christ' means messiah or savior, a traditional part of Jewish theology.
While the sacred texts of Christians, Jews, and Muslims share many historical religious stories, Christians uniquely believe Jesus to be both the Son of God and the messiah, a belief not shared by Judaism and Islam. Jesus is also recognized as 'the Christ,' suggesting his anointed role in providing salvation for humanity.
