How does faith relate to our fears as Christians?

Throughout the Bible, fear often accompanies uncertainty and trials. However, Jesus invites us to replace our fears with faith. In Matthew 14:31, after Peter doubts while walking on water, Jesus rebukes him for his little faith, indicating that our fears can be countered by trusting in Him. Romans 8:31 assures us that if God is for us, who can be against us? This underpinning of faith calls Christians to rest in the assurance of God's sovereignty, knowing that His plan is ultimately for our good and His glory, providing a foundation to stand firm against all fears.
