What does the Bible say about faith being tested?

In James 1:2-4, we are instructed to count it all joy when we face trials, as these trials test and perfect our faith. This concept is echoed in the treatment of the Syrophoenician woman by Jesus, who allowed her faith to be tested through apparent silence and insult. The testing of faith is not for God's benefit, as He already knows the hearts of men, but for our own, helping us to see the genuineness of our dependence on Him. Perseverance through these tests cultivates a deeper, more resilient faith, ensuring that we lack nothing in our spiritual journey.
