Honestly, your question seems to be a way of trying to justify sin.  We should never steal or take that which is not ours.  Ephesians 4:28 is very emphatic, “LET HIM THAT STOLE STEAL NO MORE: but rather let him labour, working with his hands the thing which is good, that he may have to give to him that needeth.”  Leviticus 19:11 says, “Ye shall not steal, neither deal falsely, neither lie one to another.”  There are many Bible verses that speak to us of the evil of stealing. 

As I read your question, I immediately thought of things you can do to prevent you from stealing.

  • Tell your employer that you cannot exist on the wages he is paying you and ask if he will give you a raise.  Of course, your employer will evaluate your work ethic to see if you deserve a raise.  I trust that as a believer, you are doing the best job you can possibly do.  We read in Ephesians 6:5-6, “Servants, be obedient to them that are your masters according to the flesh, with fear and trembling, in singleness of your heart, as unto Christ; Not with eyeservice, as menpleasers; but as the servants of Christ, doing the will of God from the heart.” 
  • Find a different job that will pay more wages that are equitable with your job skills.  If you deserve more pay, but your employer refuses or cannot pay you more, you may be better off to find a different job with a different company.
  • Augment your income by doing part-time work.  This second job could include anything that you could do that would give you more money to support yourself and your family.

To truly confess your sin of stealing would require repentance on your part.  You must realize that what you have done is wrong, it dishonors the Lord, and it hinders your fellowship with the Lord.  If you TRULY repent and confess your sin, you will have the desire to return the money you have stolen from your employer.  We learn about a tax collector named Zacchaeus in Luke 19.  After meeting the Lord, Zacchaeus repented of his sins and felt an obligation to repay those from whom he had stolen money.  He said in Luke 19:8, “…if I have taken any thing from any man by false accusation, I restore him fourfold.”  How deep was Zacchaeus that he could not even think about keeping the money that he had gotten unlawfully!  If you have true repentance for your sin of stealing from your employer, you will want to return the money to him. 

You mentioned the possibility of leaving your job but, still having the money you stole from your employer.  This makes me think there was no perceived necessity to steal from him.  If so, you would have already have spent this money on things that you need.  I encourage you to confess this sin of stealing to the Lord, return the money to your employer and confess to him what you have done.  This is a serious matter and I pray you will do what you should to make this right in the sight of the Lord, in the sight of your employer and in the sight of the law.  (456.2)
