[Influence]
The person you love most will influence you the most. Have you ever realize you become the very person yourself? Taking on the same habits, the same figures of speech and in the advance stages, be able to 'read' their mind and even react the same way they would. Isn't that why couple are always a mirror image of themselves?
The million dollar question here would be then, who do we love?

Perhaps the way of stopping sinful acts is not simply to do the right thing, but to love God. So much that He has the most influence over us, making our thoughts, our habits and our speech like His.
Making us... into Him.
