If you do not have a copy of an ESV Bible, I highly encourage you to get one! At Ref Alive, we use the ESV Bible for all of our readings on Sunday morning, both in our call to worship and in public reading of Scripture. We think it is good for our entire gathering of worshipers to read out of the same English edition of the Scriptures. (If we had pews, the ESV Bible would be our Pew Bible and available in each pew if we could afford such.)
A very basic ESV Bible available for a reasonable price is the ESV Gift and Award Bible in imitation leather. For those who can afford a little more and are interested in a Bible with helps for deepening your understanding of Scripture, I recommend the ESV Study Bible in hardback or leather. You also can download the ESV in Kindle format for the Study Bible or a plain text edition.
I am convinced that the ESV is the most accurate English translation available on the market. The ESV Study Bible is second to none in terms of its study notes, and interpretive and theological resources. However, not having an ESV Bible will not make you less spiritual. It just means that the version you are reading will sound different than the one we are using in corporate worship if and when you come to worship with us. More important than getting an ESV Bible and carrying it with you to church is that you remain faithful in your daily reading, meditation, memorization, and obedience to the Scriptures in whatever version you have.
