Not in deception or disguise

1 Not in deception or disguise
Must christians fast or pray;
But take their blessed Lord's advice,
Which is a diff'rent way.

2 The heart with godly sorrow fill'd,
Need never make a show;
Their state of mind will be reveal'd
In all they at and do.

3 They who are well convinc'd of sin,
Will feel a deep distress;
Yet differ not from other men,
In their external dress.

4 Their fastings, pray'r and abstenence,
Are fervent, and sincere;
They will not act with mere pretence,
Sad countenance to wear.

5 God will not pay a true regard,
To such a borrow'd face;
Nor grant the future great reward
To those who mock his grace.

6 The Lord is not to be deceiv'd,
All things are in his view;
Our pray'rs by him are not receiv'd,
Unless our hearts be true.
