What does the Bible say about not letting our hearts be troubled?

In John 14:1, Jesus offers a comforting command: 'Let not your heart be troubled.' This statement is not just a suggestion but a directive from Christ, who affirms that belief in God should also extend to faith in Him. The context surrounding this verse is significant, where Jesus acknowledges the impending betrayals and failures of His disciples, yet reassures them of their salvation and the eternal security found in Him. Believers are encouraged to focus on the faithfulness of Christ, who intercedes for us and whose promises will never fail, providing peace in the midst of life’s troubles.
