And according to the law almost all things are purified with blood, and without shedding of blood there is no remission(forgiveness). (Hebrews 9:22) There goes that prefix "re" again. Re, as in recover, restore, remember, etc, meaning "again and again". For Christ came to restore us bOnly the blood of Jesus could cleanse our sin and remove the shame of our actions. That's why He had to die. Remember that old hymn "What can wash away my sin? Nothing but the blood of Jesus." Jesus the man had both. Jesus Christ was both 100 percent flesh and blood man and 100 percent divine Son of God. We cannot separate the two; to do so would be to deny the work that He did on the cross. We cannot worship Christ and forget about Jesus because without Jesus we cannot have Christ. The blood of Jesus cleansed our sin and created the basis for our forgiveness, making it possible for Christ to restore us to righteousness and holiness and bring us the Holy Spirit.
This why any religion that denies Jesus has a problem. Remember everything is wrapped up in Jesus Christ and what He did on the cross. If we do not have Jesus, that means our sin is still with us.
Unless we become holy, we cannot receive the Holy Spirit.
Unless we receive the Holy Spirit, we cannot become citizens of the Kingdom of God.
