My Righteousness I hold fast, and will not let it go . . . . . Job 27:6
We lived in Alaska for 12 years and did a lot of beach-combing during that time. One thing that one can find along the beaches in Alaska is the organism that anchors kelp to the bottom of the sea floor called a "hold fast".
Here is some more information about a sea-weed hold-fast:
The root-like structure of a hold-fast.
I remember coming upon hold-fasts on the beach that were still connected around a rock and the sea weed had grown so large that during a storm the rock had come loose from the bottom and the sea weed plant had floated the rock until the whole thing had washed up on the beach. Even then the hold fast would not let go of the rock.
I also found the hollowed out cones that had washed up on the beach and dried out. In some instances they would dry out enough to use as tender for starting a fire.
The sea weed would also develop gas filled pods that would float the heavy sea weed up to the surface. Bull kelp can grow 18 to 24 inches a day.
1st Nephi 15:24
And I said unto them that it was the word of God,
and whoso would hearken unto the word of God,
and would hold fast unto it,
they would never perish:
neither could the temptations and the fiery darts of the adversary
overpower them unto blindness,
to lead them away to destruction.
May we hold fast like the kelp is my prayer . . . . . . . .
