How do we know that Martha was a believer?

The Scriptures affirm Martha's identity as a believer through several indicators. In John 11:5, we find it explicitly stated that 'Jesus loved Martha and her sister and Lazarus.' This shows that Martha was known and cherished by Christ. Furthermore, the narrative of her serving Jesus in her home and calling on Him in her distress during Lazarus's illness further signifies her belief in Him. Her actions reflect a deep-seated faith, affirming her status as a child of God who has received both His love and His teachings.
