Ezekiel 23:49 (HCSB)

They will repay you for your indecency, and you will bear the consequences for your sins of idolatry. Then you will know that I am the Lord GOD."

We must know that there are consequences even for forgiven sins. If you are a child of God your sins are under the blood. Those sins are forgiven and they are forever gone from the record. But God chooses not to protect us from the consequences of our sins here on earth. If He did that would be an encouragement to sin.

Viewing pornography can lead to addiction. Even if one does not become addicted those images are indelibly etched upon the brain. An illicit affair can lead to pregnancy. Even if one does not become pregnant there is still an emotional attachment and broken trust and broken hearts. Cheating on taxes can lead to jail time. Even if restitution is paid one will still undergo the ordeal of an audit for years. All these sins can be forgiven, but there are still consequences.

If the image of our Savior hanging on the cross is not enough to make us loathe our sin, then the prospect of the consequences should be.
