Salvation is happiness

1 Jesus has said to one and to all,
O, come unto me without money or cost!
So turn, I pray you, give heed to his call,
E'er it be too late, and you're forever lost.
Press on I pray you, till you win the prize:
How happy when that prize you shall have gained--
Peace to the soul is thus obtained--
Don't wait for tomorrow,
I know you are too wise--
And secure happiness easily sustained.
Veto your wickedness and lay it by,
In praises to God to live and to die:
Salvation, salvation is happiness,
Salvation is happiness, none can deny.
