A christian missionary Couldn’t answer| Uthman Ibn Farooq

Christians claim that Jesus Christ is the only begotten Son of God, but when we search in the Bible, we find many verses stating that God has many sons. This is a topic which this Christian Evangelical Preacher could not answer after being asked by Sheikh Uthman Ibn Farooq is Jesus the only son of God? Sheikh Uthman also asked a question: Don’t you think that the verses that talk about the children of God are just a figurative expression and not actually the biological children of God
