Things we don't understand in the Bible

What happens when we come across things we don't understand in the Bible?

We can say...

There are things I doubt in scripture, but I don't need to have all my doubts resolved to believe in God.

OR

There are things I don't understand in scripture, so I'm going to search to find the answer hidden in the Scriptures, because God put everything in there for a reason.

I vote for the second thing. There's always an answer to be found.

For example, a tough question Christians get hung up on is this...

Question: "Why did God command the extermination of the Canaanites, women and children included?"

Answer: In 1 Samuel 15:2-3, God commanded Saul and the Israelites, “This is what the LORD Almighty says: 'I will punish the Amalekites for what they did to Israel when they waylaid them as they came up from Egypt. Now go, attack the Amalekites and totally destroy everything that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys.'" God ordered similar things when the Israelites were invading the promised land (Deuteronomy 2:34; 3:6; 20:16-18). Why would God have the Israelites exterminate an entire group of people, women and children included?

The rest of the answer is here:

There's always an answer...but even if we can't always find it, we only need to be assured by the fact that God's ways are much higher than our ways, and He looks at things from an eternal perspective.
