Victory over sex sin

I love the Lord so when He started speaking to me about my besetting sin I knew I had a real struggle on my hands, it was a straight choice between a close walk with Him or my darling sin although I would still be saved.
There was a song in my head, one of those oldie's choruses, the tune was pretty naffo but the words were pure diamond. I knew the Holy Spirit was placing in my hands the key to victory, so I started singing, the song goes like this,
I have been crucified, crucified with Christ
and I live no longer I but Christ lives in me
and the life that I now live I live by the faith
by the faith of the Son of God
Who loved me, Who loved me
and gave Himself for me.
Victory was not at all immediate, I kept falling, I would get up, dust myself off and start singing, over and over, and I got victory, praise God I got free, through a song?, nah, by the mighty power that is in God's word.
