1 Beware, the Saviour gave command,
And watch ye unto pray'r;
That ye be wise and understand!
The teachers ye may hear.
2 Our Lord declares that such shall come,
Who show a pious face;
That they would come, and would presume,
To take the Saviour's place.
3 They would appear like lambs without,
But rav'nous Wolves within!
They teach and pray, and act devout:
Yet all they do is sin.
4 Their doctrine is deceit and fraud,
And of a dang'rous kind;
They do not teach the truth of God,
But please the carnal mind.
5 The truth in Jesus they deny,
It answers not their end;
Their pride and lusts to crucify
Is not what they intend.
6 As grapes on thorns have never grown,
Or figs from thistles shot;
Just so false doctrines ne'er was known,
Produce the spirits fruit.
7 The good or evil tree we know,
When of its fruit we taste;
Thus we may prove the doctrine too,
To see its fruit at last.
8 Not ev'ry one that sayeth Lord,
Shall enter into heav'n--
But they who love and keep the word,
To them it shall be giv'n.
