We have this nice kid in our neighborhood.  He is about 10 years old and has a two year old dog named Buddy.  Buddy is beautiful and weighs about the same as his master, who very faithfully takes Buddy for a walk each afternoon after school.  Maybe I should say Buddy takes his master for a walk.  Buddy is a handful and goes pretty much where he wants to go pulling his master after him. 
Buddy reminds me of strong habits and propensities in our lives.  We struggle to keep them in check but so often they pull us where they want to go.  But this I know.  There is no sin or desire so strong that we cannot overcome or control.  Unlike Buddy’s master who is doing it on his own we do not have to face temptation on our own.  Jesus’ disciple John wrote, “You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world.”  That promise is in his small letter of I John in chapter 4.  If you will put the word “overcome” in a concordance you will discover there are five promises about overcoming in I John.  John was a son of thunder and he overcame.  He was an overcomer and wants each of us to share the victory available in Jesus.
Here’s one of two promises in chapter 5. “Everyone born of God overcomes the world.”  The world is a pretty big place filled with many temptations and addictions.  But none of what the world has is bigger or stronger than the power available to us. We have overwhelming power just a prayer away. It’s even stronger than Buddy.
