I always find it interesting how temptation likes to attack when we are at our weakest. It's like it knows that we are more likely to be swayed when we are lacking in the strength needed to fight it.
This is something I've been becoming more aware of in my own life, that while I must be vigilant all the time, the time I need to really be on the alert is when I am weakest. It's in those times when I need to be constantly reminding myself of God's truth because the lies become so easy to believe.
The truth is that God is our strength when we are weak. It's just up to us to ask for that strength and then respond obediently when he prompts us to act in trust. We can trust Him to be faithful when it really counts.
