What does the Bible say about trials and testing?

In Deuteronomy 8:2, the Lord instructs His people to remember the way He led them in the wilderness to humble and test them. This concept is central to understanding the role of trials in the life of a believer. Trials expose our hearts and reveal what is truly within us. For instance, as illustrated through the experience of the Israelites, their struggles in the wilderness were designed to show their unbelief and need for reliance on God. Just as they faced physical hunger and thirst, God used these situations to teach them that man does not live by bread alone, but by every word that comes from His mouth. Similarly, Christians today can view their trials as opportunities to grow closer to God, to learn humility, and to gain a deeper understanding of His provision and care.
