The Bible is enough. It is sufficient. "Yeah but it’s just so hard to understand!" We will explore this and many other common objections dealing with the clarity of Scripture from Deuteronomy 30:11-20!
Resources and helps to better understand Scripture:
ESV Study Bible (it's like having a seminarian in your pocket!) *when you buy the print version you also get access to their online version as well!
The NLT (New Living Translation) is another good translation. The reading level is a bit lower so it's easier to read and a bit more accessible than some. Not as good for study. Great for quick devotional times.
