Desiring the Greater Gift (Philippians 4:14-23)

So, Paul wraps up this letter to the Philippian church.  What is the final desire that Paul has for them?  What is the thing that Paul wants this church to know if they never meet each other again?  What is the ultimate comfort that we take from this letter?  Does Paul want them to know that he is thankful for them giving him an offering or is Paul calling their attention beyond his ministry and their offering to him?
