To serve our death sentence for us. The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance. God does not take pleasure in punishing people, He wants everyone to come to Him in repentance and live. God gave us a choice whether we want to love Him and ask for forgiveness or not.
Most people refuse, they want to claim to be victims but never sinners.
We are all victims, that is part of living in a sinful world, but we are all guilty also. Not one of us is innocent. Even though none of us is innocent we are all victims of the very sin we are guilty of committing too. The problem is that they are not free now. They are prisoners of their own sinful natures.
