Here is a mini Bible study in song, the music for which was composed by my friend, David Boatwright, back in 1988.

Be not deceived,
God is not mocked!
For whatsoever a man soweth,
That shall he also reap.
Can a man take fire into his bosom,
And not be burned?
For they have sown the wind,
And they shall reap the whirlwind.
