Having no root, it was impossible for it to stand alone.
There is, alas, plenty of no-root religion now-a-days.

We see around us too many whose godliness is dependent on their surroundings and their circumstances.

They mean well, they try to do right, but there it ends.
They have no root; the heart is unchanged, unconverted, unrenewed.

Their religion is merely a surface religion.
So they for a time believe, for a time do well, for a time appear to be true Christians, but in time of temptation they fall away.

Their 'goodness is as a morning cloud, and as the early dew it goeth away.' If we would stand firm, we must see to it that our religion goes deep enough.
