It’s an important question. Many Christians talk like they believe the former is more powerful. They say a Christian can never really live in victory over sin this side of heaven.
They say the world will get worse over time as sinful man prevails even over the leavening work of the Gospel. They say the Gospel will not succeed on the earth until Jesus physically returns to impose His rule on mankind. Although they would never say it like this, they believe God is a loser in history.
I don’t see how that can be. If you are a Christian, the same Spirit that raised Jesus from the dead dwells in you. (Romans 8:11) The same Spirit that defeated death can defeat sin. The same Spirit that changed you can change the world.
So, which is more powerful? It’s a simple question. GS
