Matthew 13:21
Yet he has no root in himself, but endures for a while, and when tribulation or persecution arises on account of the word, immediately he falls away. The rootlessness is the defining condition of the rocky-ground person: no root means no capacity to sustain through the drought of persecution. The immediately falls away mirrors the immediately receives in verse 20 — the same emotional immediacy that characterized the initial reception characterizes the falling away. Depth of root, not height of initial excitement, determines the response to tribulation.
