This Scripture specifically deals with immorality and adultery…but in the bigger picture, it deals with sin against God.  Have you ever considered that every time you sin – you’re  defying God to His face?  For every time you allow evil to reign in your life, you’re in direct opposition to God and rebelling against Him.  Joseph understood that giving into a temptation was a sin…but that sin isn’t self contained…for no matter how hidden we think it is, others will be affected by our lack of judgement.   And ultimately, Joseph knew he would be sinning against  God.
