The cost of God’s act of self-sacrifice was great. Paul reminds us that we are bought with a price and that price is the very blood of the Son of God, Jesus Christ. The writer to the Hebrews tells us that there can be no forgiveness of sin without the shedding of blood.
Through his death on the cross, the shedding of his own blood, our rebellion towards God, our sin, is dealt with. We are redeemed.
Redemption is all about buying something back, making an exchange. Jesus exchanged his life for our lives, through his death he takes on his own shoulders the judgement we rightly deserve.
Communion is a remembrance of the sacrifice made by Jesus on our behalf and a celebration of his victory over sin and death.
