Thank you for your post.
I think you’re right about not seeing this as either-or. It is a mindset we must be watchful for in our lives. But, as far as what is over the thrown of our hearts, only one can be God, the #1 priority. The key is, as you said, to use the gift God has blessed us with in partnership with Him.
On the topic of priority, I hear quite a bit that if writing (or any other endeavor) is critical to an individual, they should make it a priority. How can we balance making progress on our projects without creativity becoming the ultimate priority over God?
