Do you remember the story of Adam and Eve and what happened after they ate from the Tree of the Knowledge of Good and Evil?  They felt ashamed and hid themselves.  Their sin had placed a barrier between them and God, and they innately knew this.  The same is true for us when we sin.  Isaiah 59:2 says that our sins create a separation between us and God.  Even if you don't see the immediate earthly consequence of your lie or your deception or whatever other sin you commit, there's a deeper spiritual consequence that only exacerbates the problem further.  That's the problem with sin.  Beyond the earthly consequences, broken relationships, and mistrust, there's a separation between you and God.   The only way that this separation can be fixed is through Christ's death.  When Jesus paid the penalty for our sins, the separation was bridged.  The Navigators came up with an illustration for this concept.  The big question to ask yourself is whether or not your have accepted Christ's death so that the separation between God and you is taken care of.
