Why Genesis? The pat answer is that it is beginning of everything that God has done. Everything we read from Exodus on, including and especially in the Gospels, can be traced right back to the first instance in Genesis.
The real answer is that this is a sincere challenge and I want to walk through it.
Here just the very small list of resources on Genesis that I have found most helpful.
Christian Standard Bible
Holmon Publishing. 2020.
Many times, many teachers, preachers, and small group leaders (myself included) will "cut straight to the chase" and engage the commentary instead of engaging the Word of God. Remember, the commentaries are not without error—they are the observations of the author.
Slow down, pray, read, chew and meditate.
ESV Reformation Study Bible
Commentary & Edited by R.C. Sproul.
Ligonier Ministries. March 16, 2015.
I don't have much to say except this: if I was restricted to one Study Bible, this would be the one. Even if they never make one for the CSB. That is how much I love R.C. Sproul's notes--they will always refer back to historical creeds and confessions.
ESV Study Bible
If I had to pick just one format (hardcover vs. leather vs. paperback vs. digital), I use it way more in my Olive Tree Study Bible than anything else.
Hebrew Greek Key Word Study Bible.
New American Standard Bible 1977.
AMG International. 2008.
Spirit of the Reformation Study Bible.
Life Application Study Bible.
I don't have a personal insightful recommendation on the following. I just wanted to have a stack of resources that I can check by and draw from if I need to.
James Montgomery Boice.
