So a Christian who lives in this confidence toward God,
Knows all things,
Can do all things,
Undertakes all things that are to be done,
And does everything cheerfully and freely;
Not that he may gather many merits and good works,
But because it is a pleasure for him to please God thereby,
And he serves God purely for nothing,
Content that his service pleases God.

On the other hand,
He who is not at one with God,
Or doubts, hunts, and worries
In what way he may do enough and with
Many more works move God.

In summary
Just do what you can
Ultimately it is not our works
We all have all fallen short
Be content to serve God humbly when you can
It is only his Grace that saves us
