Amy G., thank you for the link to J. Mac's website.

Lou M.: After reading what J. Mac says I see the following.
He affirms salvation is by grace through faith with no human works involved.
He affirms there is no "preparation work" before salvation.
He says what I thought he was saying from the quotes you gave, that commitment to follow Jesus Christ always accompanies true saving faith.
He absolutely does not say a person must have an "upfront" commitment to follow Christ prior to salvation. In fact, he clearly rejects the notion.
Concerning the James 4 quote. You base argument on J. Mac calling v.7-7-10 an invitation to salvation, whereas James was written to believers.
But the context of James 4 goes directly to J. Mac's argument that following Christ accompanies salvation. James has already scolded the professing believers as being "friends of the world and enemies of God". V. 6 says "God is opposed to the proud, but gives grace to the humble".
James is clearly speaking here of two different kinds of people. God is opposed to one (unsaved, proud, and of the world) and to one God is giving grace to (the humble, not of the world, saved).
It is in that context that the verses 7-10 come. James is concerned with what saving faith should look like, how it is expressed among the believers. v.7-10 expand on that. J. Mac's exposition of the passage is quite good, and certainly reasonable in the context given.
I believe you are misrepresenting what J. Mac says on this issue.
peace to you
