There is Power in the Blood of Jesus
The blood of Jesus Christ has redeemed us back to the Father. In the Old Testament, the Israelites had to offer animal sacrifices to atone for their sin. However, an animal sacrifice would not cover their sin for all time, which is why they constantly had to go back to the temple to offer new sacrifices to God.
When Jesus gave His life for us, His blood was so powerful, it covered all of our sins for all time. There is so much power in the blood of the sinless Lamb of God that laid down His life willingly for those who love Him.
