Modern man considers himself more just than his ancestors, for abolishing the death penalty. Actually, he doesn’t value human life, for justice requires that the punishment fit the crime. In the same way, also, people today don’t understand the seriousness of sin nor the price necessary for redemption.
So even the first covenant was inaugurated with blood.
Hebrews 9:18 NET
There’s nothing more serious than transgressing God’s law and thus rebelling against him. In its essence sin is worse than killing another person, for the price of redemption is death.
How great is God’s love for us, to the point of sending his Son to die in our place!
