One of Satan's best lies is that what we do today will not effect tomorrow. He tells us that just because we are doing something wrong doesn't mean we will have to suffer. This lie, causes people to do things without thinking of the consequences of their actions. The sad part is Satan's main vehicle for this lie is the media.
I'm sure you've heard of the country song where a guy goes to pick up a girl, the girl's dad doesn't like him, they leave and he tries to figure out what he was thinking. The verses go on to say that he knows there will be consequences, but all he's thinking about is the girl. Another example of the media being soaked with this lie of Satan's are all of the one night stands in movies where everything turns out honky dory.
The truth must be exposed! If there wasn't a tomorrow then we wouldn't have to suffer for the consequences of today; the problem is that there is a tomorrow and we will suffer the consequences. When we believe Satan's lie that what we do wrong will go unpunished, we are willingly being ignorant of God.
1 Corinthians 15:34 says, "Come back to your senses as you ought, and stop sinning; for there are some who are ignorant of God-I say this to your shame."
The best way for us to see through Satan's lies is to grow deeper in our relationship with Christ. The best way to do this is to read your Bible and to soak in all of what God want's in our lives. Pray specifically asking God to help you know His truth from Satan's lies.
Jeremiah 10:23, "I know, O LORD, that a man's life is not his own; it is not for man to direct his steps."
