The key to doing good is being full of and controlled by the Holy Spirit.
Application
God gives aid and support to everything I do and say.
God gives me the strength to accomplish good things.
God makes me competent, able to do and say good things.

I rely on God for everything.  Every good thing I do is dependent on the Holy Spirit.  Every good thing I say is dependent on the Holy Spirit.  The Holy Spirit is the divine enabler.  He empowers me to do good.  He empowers me to speak.  I need a daily fresh filling of His Spirit.  Empowering comes through abiding.  The key to doing good is being full of and controlled by the Holy Spirit.

Prayer
I rely on you for everything. I ask that you comfort and strengthen me in every good thing I do and say.

Fill me afresh and anew with your Spirit today.
