There’s no doubt about it, adultery can be attractive .  The temptation of the forbidden, the promise and allure of a new experience.  In September 2009 a survey of 3,000 people suggested that 40% of women and 30% of men have cheated on their partners.  A third of the women suggested that their indiscretion had happened because their flirting got out of hand.

The pain and damage of unfaithfulness is massive.

Which is why the language surrounding the unfaithfulness of God’s people is so stark.  “They whored after other gods,” in the ESV or they “prostituted themselves to other gods,” in the NIV translation of Judges 2:17.

When God’s people worship other gods, they are cheapening themselves on a grand scale and causing huge damage to the most intimate of relationships.  They are breaking the most important commandment.  It is the most serious sin.  And so often it is because flirting has got out of hand.  OK, not many of us bow down to wooden poles these days but the gods of the modern world are many and the chances are you’ve flirted with some of them.  What starts as a casual, thrill seeking experience becomes idolatry.  Before you know it, you’re being unfaithful to the LORD.

And God does not ignore unfaithfulness.  He doesn’t turn a blind eye.  God deals with it.  “Whenever they marched out, the hand of the LORD was against them for harm,” Judges 2:15.  That’s uncomfortable reading isn’t it?  We don’t like to think that God would do that – that He would deal with His people like that.  But our God is a jealous God.  He loves us and He will not tolerate rivals.

The LORD is the only true God, the only one worthy of our worship.  We have the most amazing relationship with Him through faith in the saving work of Jesus.  If we want to be secure in a changing world, faithfulness to the unchanging God is the only sure way.  Don’t worship another god.  Don’t even flirt with one.
