Even Good Ground is not guaranteed a full harvest.

Even Good Ground is not guaranteed a full harvest. Mark 4 20 But these are the ones sown on good ground, those who hear the word, accept it, and bear fruit: some thirtyfold, some sixty, and some a hundred. Last week we looked at the wayside, stony ground and thorns. Good ground then is without stones and thorns and is in The Way (close to Jesus). Here is the difference - these ones hear and accept The Word. Accept (Greek) - Receive, allow entrance, take to yourself. It is mine. Then they bear fruit, but not all the same amount of increase. So if 100 fold is possible, what can prevent that from happening?
