Jesus would be the first born, and has preeminence (https://www.blueletterbible.org/faq/don_stewart/don_stewart_216.cfm https://www.blueletterbible.org/faq/don_stewart/don_stewart_...). Christians, when they enter into the family of God are adopted (in the roman sense). Jesus is different because He is God, because He was first, because when He lived on this earth He did no sin and thus when He died his sacrifice was sufficient for sins that were not His own, and because He was God, His sacrifice was sufficient for the sins of all mankind. Our deaths must atone for our own sins and can't be applied to another. According to Christian doctrine, our deaths are not permanent, as all people will be resurrected, either to live with God or to suffer punishment for rejecting Him.
