In the old testament, the Israelites would have to sacrifice a year-old male goat or sheep without a defect or blemish, to atone for their sins. God asked for their very best because down the line God would give us His very best, Jesus Christ of Nazareth. Deuteronomy 12:23 makes it clear, that the blood is the life, therefore you have gained life. Not only have you gained life, but you have access to all things: healing, mercy, grace, prosperity, and forgiveness. Remember that who the Son sets free is free indeed; and where sin abounds, grace much more abounds.
Romans 8:32 He who did not spare his own Son, but gave him up for us all—how will he not also, along with him, graciously give us all things?
