We casually toss around the word grace in so many ways. Saying thanks before a meal, a name on a church, or a greeting in the Bible.
There are both common and specific forms of grace.
Saving grace is very “generic” (not cheap but similar for all). Grace for life is where it becomes unique.
“According to the grace of God given to me, like a skilled master builder I laid a foundation, and someone else is building upon it. Let each one take care how he builds upon it.” 1 Corinthians 3:10
Paul is speaking of a specific grace given to him for the completion of the job God had for him.
We use words like calling, leading, prompting, or the will of God. We know these things are unique.
Here Paul says this is the specific grace given to aid us in doing what we are made for.
