False, they were never saved, had no root and had hard hearts. It tells you that if you study the different soils Matt 13 20-21
20 But he that received the seed into stony places, the same is he that heareth the word, and anon with joy receiveth it;
21 Yet hath he not root in himself, but dureth for a while: for when tribulation or persecution ariseth because of the word, by and by he is offended.
Lk 8 13
They on the rock are they, which, when they hear, receive the word with joy; and these have no root, which for a while believe, and in time of temptation fall away.
Their believing was superficial and not the Gift of God, no Christ in them, He is the root
It says the word fell on hard stony ground, thats an unregenerate hard heart, God gives a new heart in regeneration Ezk 36:26
26 A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
