For most of my husband’s professional career, he worked as a lab technician and then a lab manager, first in the textile industry, then in plastics.

Part of lab work involved troubleshooting problems as they came up. But when the company developed new products, they had to be tested.

In automotive textiles, for instance, fibers and fabrics need to maintain their color despite being hit with bright sunlight for years. So the lab had a weatherometer to simulate so many days of sunshine to see how soon the fibers would fade.

Other tests involved metameric properties: looking the same color in different lights. Automobile manufacturers wanted a car’s color to look the same in sunlight, under the showroom’s fluorescent lights, and in the homeowner’s garage with incandescent lighting. There was a brief exception to this for a time when some cars were deliberately painted to look like they changed colors as they passed. But even then, I believe the interior colors remained the same.

Fibers were also tested for tensile strength: their ability to be stretched or pulled without breaking.

Sometimes were tests were diagnostic. The technicians needed to know the properties of the fibers to discover their weaknesses in order to strengthen them or improve them.

God might test people for the same purposes. He knows our weaknesses and whether we will pass or fail our tests. But often we don’t know until we fail. Like Peter before Jesus was arrested, we feel confident in our devotion to Him. We’re even warned to watch and pray, and, like Peter, fall asleep instead. And then when the temptation comes, we fall on our faces and weep bitterly.

But when we fail a test, God doesn’t reject us or pull us off the assembly line. He uses the failure to make us aware of our need for dependence on Him. If we respond in the right way, we draw even closer to Him because we realize how much we need Him.

However, some tests don’t expose weaknesses: they reveal strengths. Manufacturers like to advertise that their products have passed tests. College entrance exams show that a student is ready to handle the challenges of university learning. Military, police, and firemen all have to pass rigorous tests to prove they can handle their jobs.

When God pointed out to Satan that Job was a righteous, godly man, God knew how Job would respond. Though knocked to the dust in sorrow and coming to some wrong conclusions, Job’s faith never faltered. Even when he questioned God, he was still expressing trust in him. His example of facing intense suffering has encouraged Christian for centuries.

Likewise, Joseph endured the cruelty of his brothers, being sold into slavery, falsely accused, and forgotten, with a grace few of us could manage. His conclusion that God meant for good what his brothers meant for evil has helped many Christians come to the same understanding and to trust God even when life seems unfair and doesn’t make sense.

Sometimes our tests are not just for us. When we see how others weather their tests, we’re encouraged that surviving and thriving are possible. That’s why we listen when someone like Joni Eareckson Tada speaks. She’s been through the fire and found God faithful and good.

Being a good testimony through our tests doesn’t mean putting up a smiling front or keeping a stiff upper lip. The psalmists poured out their confusion, frustration, and fears to God. It helps to read that others have wrestled with the same questions and feelings we do. That’s part of their testimony as well as the resolutions they come to.

If fibers were sentient, they might consider the tensile test was torture. But the technician isn’t being cruel. He doesn’t want to destroy the fiber. He doesn’t want it to fail. He has every hope that it will pass the test so that it can perform the function for which it was created.

God does not test us in a clinical or dispassionate way. He has our best interests at heart. He wants us to grow and develop in the best way we can. Like a parent, coach, or teacher, He stretches our endurance so we may grow stronger and more dependent on Him. He wants to show others, through us, that His grace is sufficient.

The Bible encourages us to endure testing joyfully:

Count it all joy, my brothers, when you meet trials of various kinds, for you know that the testing of your faith produces steadfastness. And let steadfastness have its full effect, that you may be perfect and complete, lacking in nothing (James 1:2-4).

In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, so that the tested genuineness of your faith—more precious than gold that perishes though it is tested by fire—may be found to result in praise and glory and honor at the revelation of Jesus Christ (1 Peter 1:6-7).

We rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope, and hope does not put us to shame, because God’s love has been poured into our hearts through the Holy Spirit who has been given to us (Romans 5:3-5).

And when the tests are over:

And after you have suffered a little while, the God of all grace, who has called you to his eternal glory in Christ, will himself restore, confirm, strengthen, and establish you (1 Peter 5:10).

Blessed is the man who remains steadfast under trial, for when he has stood the test he will receive the crown of life, which God has promised to those who love him (James 1:12). 

Will our faith remain vibrant, or fade under pressures and trials?

Will our colors remain true, or change with circumstances?

Will we endure without breaking?

Not in our own strength. But “I can do all things through him who strengthens me” (Philippians 4:13).

May God give us grace to endure testing for His glory.
