God Tests Hearts

===

The crucible is for refining silver and the furnace is for gold, likewise the Lord tests hearts.

Proverbs 17:3 (NET)

===

So this verse came up in my quiet time this morning.

After the struggle I went through on yesterday’s verse (2 Chron. 32:31) I thought it worthwhile to look at this one.

Let’s start with the imagery.

A crucible is designed to get white-hot, melt metal, and destroy impurities in the metal.

Unlike the metal, a crucible will keep its shape. It can withstand extreme temperatures. For reference, silver and gold melt at 1,763°F and 1,948°F.

That’s intense heat.

The metals lose their form, any impurities burn away, and they’re free to be re-shaped into whatever the master smith decides.

I’m sure you can see the metaphor here.

Likewise, God tests hearts.

This isn’t necessarily a “get saved” thing. Jesus’ death has already covered our impurities.

But if God wants to re-shape us into looking like Christ, and remove stubborn impurities along the way, then He’s probably going to melt us in the crucible.

He doesn’t leave us alone.

We have a Comforter.

The Holy Spirit living within us, helping, guiding, and comforting us.

As crazy as it might sound, its almost a blessing to be considered worthy to be tested by God -- knowing that He’s confident we will come out the other side looking more like Christ.

Of course, no one wants to endure those trials.

But consider it joy when they come, God is making us steadfast in Him.
