In the Bible blood symbolizes life. The life of the flesh is in the blood. Sin brings spiritual death. When Christ showed His love for others by shedding His blood it was to bring the dead back to life and give eternal life to all those who trust in Him. The reasons why God delights in the suffering and death of Christ isn’t because He’s a sadistic blood freak. It’s not the suffering and death of Christ in and of itself that pleases God. Rather, it’s what the Son accomplished with His bloody death in showing love for the Father and sinners. What is so precious about the blood is that by it we are healed and cleansed as we are given new life. That’s what pleases God about the love sacrifice and obedience of Christ. It’s not the blood in and of itself. Because our sins are cleansed, expiated, and covered God is pleased. Christ loved and gave Himself up for us, a fragrant offering and sacrifice to God. - Ephesians 5:2
