What does the Bible say about being troubled?

In John 14:1, Jesus tells His disciples, 'Let not your heart be troubled,' highlighting that amidst difficult circumstances, believers can find peace in their faith. The troubles we face—whether from personal struggles, loss, or fear of the future—can weigh heavily on us. Yet, Jesus assures His followers to believe in God and in Him, emphasizing the security and comfort found in a relationship with Him. The call to not be troubled is closely tied to a deep trust in God's sovereignty, His constant presence, and His perfect plan for us.
