In response to the question posed in the title, the only action one may execute in order to do God's will is to make himself available..........He does the rest.
Now the question..... how many WILL if they believe it's not required? If I had been sold this doctrine early on & swallowed it all, no way would I ever force myself to do something I never had to do before. If I didn't believe in conviction & repentance, I'd never do it, for it's the Spirit's leading that prompts it.
Availability = willingness & that equals faithfulness & that equals serving the Lord as a servant.
Why do all that? That sounds hard..... like work. And it is.
If a person believes works of any kind with the Holy Spirit epowering the believer to do so isn't required, how CAN there be the fear of the Lord in them? In the beginning, maybe, but once they settle down & no fear of God in their eyes, if any coldness sets in, it's over.
There's no christian, especially myself, that hasn't dealt with spiritual coldness.
Good post, though.
