Even if you say the blood of Jesus equals Jesus, that still doesn't show that we can cleanse ourselves from our sins by obedience, or that the law can cleanse us from our sins. (You wrote: "Obey them and they will cleanse you from your sins.") Only Jesus can cleanse people from their sins The law could not do that:
“2 For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death. 3 For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, 4 that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit.” (Ro 8:2-4 NKJV)
