How to fail a wife

I've already said I've not been a good husband. But even my worst mistakes don't come close to Adam, someone whose marital failure caused the downfall of the human race. Don't get how Adam and Eve's failed marriage was responsible for the sin we all suffer? Then you might want to read this article

Here are some points that hit me:

• How many homes have crumbled because husbands failed to see temptation for what it is and call sin what it is? The surest way for a man to protect the home around him is for him to guard the heart within him. 
• Guardians of the home don’t just stand on the wall, scanning the horizon for shadows; they also fill the walls with light. They know that a family’s best defense is a deepening and expanding joy in God, that some of the best keeping happens through consistently reading, sharing, praying, marveling, serving, and singing. [Which is why... A family that worships God together is a strong family - words Janet uses to Peter]
• Our homes and churches need husbands and fathers who refuse to abandon God’s word, even if their wives, children, and friends come to lead them away.
• How many husbands today, like Adam, have lowered our guards and let temptation invade and live freely in our homes? How often have we let Satan’s lies go unchallenged — or worse, undetected? Being a husband means standing guard before serpents come.
