John Wesley on Hebrews 9:26

For then he must often have suffered from the foundation of the world - This supposes, That by suffering once he atoned for all the sins which had been committed from the foundation of the world. That he could not have atoned for them without suffering. At the consummation of the ages - The sacrifice of Christ divides the whole age or duration of the world into two parts, and extends its virtue backward and forward, from this middle point wherein they meet to abolish both the guilt and power of sin.
