Have nothing to do with irreverent, silly myths.
Rather train yourself for godliness.
–1 Timothy 4:7 (ESV)–

Thou shalt have no other gods before me. 
Thou shalt not make unto thee any graven image.
–Exodus 20:3-4 (KJV)–

We did not follow cleverly devised myths
when we made known to you the power
and coming of our Lord Jesus Christ,
but we had been eyewitnesses of his majesty.
–2 Peter 1:16 (NRSV)–
