You can have certain knowledge of some aspects of God's character and not necessarily have certain knowledge of other aspects. It is not irrational to hold to knowledge of God or an appreciation of God's goodness in the face of difficult issues.
It is indeed prideful to assume that there must be every single issue resolved in knowing the Bible. However, there is so much written on the scriptures, there are so many books. If you are looking for a Christian perspective on Biblical difficulties, it is in your reach to find it. Look up authors like FF Bruce, NT Wright, Alaisdair McGraph, Alvin Plantiga, Zondervan publishing, etc
