It appears to me that your always on guard, which is excellent!
I know that your familiar with this verse in scripture.
1 Peter 5:8 - Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
I remember a time when I first garbed myself with the Full armour of God or almost full, and immediately when my eyes were set off the Target which is Jesus, I lost direction and fell victim to satan and his demons.
The demons are assigned to the persons particular sin and uses the sons of disobedience or unbelievers as vessels to ensare any in that weak spot, I remember a verse or commentary within a bible which stated that a chain is only strong as its weakest link and that is where they target, i'm sure that you know all this already.
God Bless!
