I was in my small study room when all of a sudden one of my shelves went crushing down. The support of the shelf eventually gave way to the weight it is carrying. This is an example of basic physical law. The holder or support should be able to carry its load. If not something will collapse.
This is true also in the spiritual realm. If our belief is not supported by truth then our belief will fall down too or will not save us.
Have we checked our beliefs or system if they are supported by the Bible ?
Take time to pray for truth and God will lead us to truth.
