How does the story of Lazarus illustrate faith and unbelief?

In John 11, we see both faith and unbelief vividly displayed through Martha’s and Mary’s interactions with Jesus. While Martha expresses a degree of faith by acknowledging that Jesus can still help, she simultaneously reveals her doubts about His ability to raise Lazarus now that he is dead. This duality showcases the struggle many Christians face — believing in God's power and yet wrestling with doubts due to circumstances. Jesus patiently addresses this tension, reminding Martha that faith involves trusting in His identity as the resurrection and life, thus encouraging believers to embrace faith over fear.
