There is a distinct difference between rushes and trees.
The first audio sermon is about comparing a person’s life to either a rush or a tree. There are a differences in the nature of rushes and that of trees. There is also uncanny likenesses in a believer’s spiritual nature to either a rush or a tree.
The second audio sermon is about the nature difference between trees, and the similarity between them and the believer.
The third audio sermon is about the two trees in the garden of Eden. The one representing the old covenant and law (the knowledge of good and evil) that brings death, and the other representing the new covenant of grace and a tree that brings life.
