The next progression in lying is to lie when there is something to be acquired. This type of lie can range from trying to make someone else look bad to scheming to obtain something that cannot be had in a way that pleases God. In both situations the reason for the lie is the same — self-centeredness. But in this second type of lie, the reason for the lie moves beyond mere self-protection to the point of lying to achieve personal desires, even if it means hurting others. So, you see the progression. This is not simply lying to avoid punishment. This type of lying bears a close connection with the ways of darkness (Eph. 2:1-3). This lie represents a scheming, crafty motivation. This is deceit reaching maturity. Often a young child will blurt out a lie that is foolish – with cookie crumbs all over his face and shirt, your son says, "I didn't eat the cookie, Mommy." The scheming liar, the crafty one, makes sure his face is clean and the cookie crumbs are on his sister's shirt when he lies.
There is real danger here. You must be vigilant to detect the shift to this second type of lie. This where scheming and deep heart issues will grow and fester into youthful lusts.
