My training for the long-distance race was going badly, and the latest run was particularly disappointing. I walked half the time and even had to sit down at one point. It felt like I had failed a mini-test.
Then I remembered that this was the whole point of training. It was not a test to pass, nor was there a grade I had to achieve. Rather, it was something I simply had to go through, again and again, to improve my endurance.
Perhaps you feel bad about a trial you are facing. God allows us to undergo these times of testing to toughen our spiritual muscles and endurance. He teaches us to rely on Him, and purifies us to be holy, so that we become more like Christ.
No wonder the psalmist could praise God for refining the Israelites through fire and water (Ps. 66:10–12) as they suffered in slavery and exile. God not only preserved them and brought them to a place of great abundance, but also purified them in the process.
As we go through testing, we can rely on God for strength and perseverance. He is refining us through our toughest moments.
