I just feel inclined to think so but I am not sure exactly what makes me think that way. It might be hard for Jesus to remain free of sin with siblings to contend with all the time.
One of the texts left out of the New Testament allegedly tells stories of Jesus before his ministry in his 30s. Allegedly, as a child he used his powers against other children. (as any "normal" kid would do with super powers)
Yeah, but I can see Jesus and His three sisters Marcia, Jan and Cindy. And frustrated Jan saying to Mary and Joseph, "Well, all I hear all day long at school is how great Jesus is at this, or how wonderful Jesus did that. Jesus, Jesus, Jesus . . . "
God does have more than one son and a couple of daughters but only one begotten Son. In an amazing display of His love and mercy, the Father is pleased to make us (born-again men and women) His children.
"Behold what manner of love the Father has bestowed on us, that we should be called children of God"! (1 John 3:1)
God gave His only begotten Son to die in our place so that we might be adopted as sons (Ephesians 1:5; cf. Galatians 4:4–5). As children of God, we have a place of glory with Jesus Christ. And because God has adopted Christians (born-again men and women) the world is a better place.
"The Spirit Himself bears witness with our spirit that we are children of God, and if children, then heirs—heirs of God and joint-heirs with Christ, if indeed we suffer with Him, that we may be glorified together". (Romans 8:16-17)
