It was pretty much what I expected from John MacArthur, but that didn’t stop me from being disappointed in the book. He didn’t even pretend to offer practical guidance. The book’s message was 1) God’s will is in the Bible, 2) obey the Bible, 3) do what you want (while doing #2). Read Kevin DeYoung’s Just Do Something instead, who at least talks about the importance of developing godly wisdom to make decisions.
But really, the bulk of the book simply looks at verses that explicitly say, “this is the will of God” and talks about what those mean. This is as reductive as you could possibly be about the will of God, rather than even mentioning about God’s moral/revealed will and what the Christian ethic consists of beyond these verses. Then, the only principle he gives outside of what is explicitly in Scripture, is “do whatever you want.” That’s hardly a solid basis for living a morally exemplary life.
Chapter 1 - God's will is in the Bible
Chapter 2 - God's will is for you to be a Christian and to share Christianity with others (1 Timothy 2:3-4; 2 Peter 3:9)
Chapter 3- be spirit filled (Ephesians 5:17-19) and filled with the Word
Chapter 4 - be sanctified (1 Thessalonians 4:3)
Chapter 5 - live a lawful and exemplary life in the eyes of ordinary men (1 Peter 2:13-15)
Chapter 6 - boldly confront the world with the Gospel and stand firm in suffering (1 Peter 3:17; 4:19)
Chapter 7 - do whatever you want
I think his arguments are (badly) mistaken at times. For example, he criticized people for praying for more of God’s Spirit, grace, or to increase our love for others, quoting Bible verses that are supposed to imply God has given all of these that we need. In addition to being obnoxious-first-year-seminary-student levels of pedantic and clearly missing the point and meaning of these prayers, he is simply wrong. MacArthur critiques, “You pray, ‘God, give me more love for so-and-so.’ The Bible says the ‘love of God has been poured out within our hearts’ (Rom. 5:5)”. So, apparently, the love of God being poured out in our hearts implies our love for someone cannot increase. While these two things are not even remotely contradictory, his criticism contradicts a different Bible passage! 2 Thessalonians 1:3 has Paul thanking God because “your love for one another is increasing”. If Paul can thank God for increasing one’s love for another, then I think it’s a legitimate thing to pray for.
I also think his lengthy discussion of submitting to human authorities and obeying laws even when you don’t like it is quite ironic given his whole escapade with his blatant disobedience of COVID restrictions, which did the exact opposite of “silence the critics” that he thinks is important. I guess he thinks COVID restrictions were a direct violation of a command by God, although I don’t believe I have read in the Bible to “make sure you do not change anything about your church meeting habits, including physical location and spacing, even if there is a deadly outbreak of a rapidly spreading illness,” but maybe I missed that Bible passage in my reading.
In the final chapter, he reviews Paul’s decision-making during his missionary journeys in a strange way that totally ignores the difficulties these present to the naïve decision-making procedure that MacArthur recommends. While Paul does not seem to be waiting around for magical voices from God, there are obvious passages in Acts that are worth at least acknowledging are not in line with MacArthur’s suggested simplistic procedure. Acts records audible voices, disciples casting lots, Spirit promptings, angelic appearances, and a vision with exact instructions, for example. These aren’t “normal”, but at least deal with them! When MacArthur does mention Paul being “prevented by the Holy Spirit from preaching the word in the province of Asia”, he simply says, “We don’t know how God stopped them, but He did.” Great. Is that totally irrelevant to my life? Will it always be incredibly obvious to me, as obvious as it was to Paul? I have no idea, as MacArthur said nothing else. Again, here I think Kevin DeYoung’s discussion in Just Do Something is much better, adequately dealing with problematic passages in Acts while satisfactorily building a case that Paul was primarily relying on what “seemed good to us” (Acts 15:28) or what opportunities arise (1 Corinthians 16:7-9).
In summary, MacArthur says that “God’s will is that you be saved, Spirit-filled, sanctified, submissive, and suffering”, and assuming you’re doing that, do what you want. That’s a really big assumption, whether I am doing all those previous things, which affects the relevance of the suggestion of following my desires. There is a huge question of the extent to which my desires are adequately representing God’s own desires. While my desires surely count for something on their own, and, hopefully, they are generally in line with God’s desires, this guidance is not very helpful nor am I confident that this is the key to making decisions in the Christian life.
