1 Samuel 4-6

These chapters talk a lot about the Ark of the Covenant. After defeating the Israelites in battle the Philitines capture the Ark and bring it to three different city having to move it often because the Lord gives the people tumors in each of the Philistine cities. [Tumors, ha. One part said tumors of the groin. Lord, interesting choice...] Eventually they give the Ark back! And then even when it's back on Israelite territory God kills 70 people for looking inside!
I question what this means? Why? Was God just displaying His power and might? Creating that fear? I mean my guess is as good as the next...
God show me what this means & how I can apply it my life. Let me be changed by your word.
