I have decided to do option number 1, using the Gospel of John.
John was written by John the son of Zebedee. John is commonly referred to as "the disciple whom Jesus loved" as we see in John 13:23.
The Gospel of John tends to stand out as the Gospel that shows us that Jesus is unique as God's special son, yet He is still fully God. This is the reason why John is so often the Book of the Bible that Christians use to witness to unbelievers. John is also widely considered to be one of the best books for new Believers to read, as it gives us a complete picture of how unique Jesus is. John shows us, clearly, that Jesus is God's eternal son and the Light of the World; because He offers the gift of eternal life to all people. This is shown in John 8:12 which says "I am the Light of the World. Whoever follows Me will never walk in darkness, but will have the light of life". John clearly shows us that not is Jesus the Light of the World but He takes away the sins of the world. He would not be able to do this unless He is God's eternal son. John also shows eight specific signs, or miracles, that shows us Jesus power and love. He would not be able to perform these miracles unless He was the Son of God. John was specific in the miracles that he wrote about. As we see in John 20:30-31 John says "Jesus perfomred many other signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name".
