For it is God who is working in you, enabling you both to desire and to work out His good purpose. (HCSB)
For it is God who is working in you both to will and to work according to his good purpose. (CSB)
God will continually revitalize you, implanting within you the passion to do what pleases him. (TPT)
For it is God who works in you to will and to act in order to fulfill his good purpose. (NIV)
Whichever translation you choose, it's all really really encouraging news! It's not all up to me and I'm not alone! Truly he is our help and our provider. God himself is working in and simultaneously willing, enabling, implanting in me the desire for his will and purposes but he will too act and carry out his good purposes and will in and through me. So if I just show up... if I have as small as a mustard seed... if I say "yes" even if a small, faint and whisper what can he not do and what will he won't do!?!
Surely God desires his good plans for our lives more than we could ever desire for ourselves. So I hope in him and place all of my faith, confidence and trust in his ability, strength and power. Simply amazing.
