Sir Isaac Newton (1642-1727), that great English scientist, discovered three important "laws of motion." The third one states that "for every action there is an equal and opposite reaction." This principle was used in space exploration. We learned to use powerful thrust rockets burning fuel to propel space capsules through earth’s atmosphere and into space.
A spiritual reality can be compared to this law of motion. For each action against God, there is a reaction. When we sin, there must be punishment. Since God is true to His nature, He will not over ride that law. Yet, as opposing forces were found and marshaled to overcome the force of gravity to allow space travel, hell is not the necessary end of every person. Because God loved us so much, He intervened and allowed Jesus to take our punishment for us. He took the "reaction" our actions
deserve. Praise God that believers are no longer under the law but under grace.
