Soiled?

[An addict] is like a tree that bends easily in the wind. On a windy and rainy day, the tree bends so deeply against the ground that the leaves become soiled with mud, like sin. If we focus only on cleaning the leaves, the weakness in the tree that allowed it to bend and soil its leaves may remain. Similarly, a person who is merely sorry to be soiled by sin will sin again in the next high wind. The susceptibility to repetition continues until the tree has been strengthened. Dallin H. Oaks
