What does the Bible say about trials and testing in faith?

Trials are sent by God with His knowledge to serve His purposes. They are designed to test our responses—will we doubt the Lord's goodness or trust Him more? As outlined in Proverbs 3:5, we are encouraged to trust in the Lord with all our heart and acknowledge Him in all our ways. God uses these experiences to guide us, teaching us to lean not on our own understanding but on His wisdom and provision. Each trial can strengthen our faith, prompting us to turn to Him and recognize His sovereignty in both difficult and abundant times.
