Mark 3:15 (KJV)

What does Mark 3:15 mean?

Mark 3:15 says that Jesus gave his chosen followers the authority to heal people who were sick and to drive out evil spirits. This verse highlights the special power and responsibility Jesus entrusted to his disciples as part of their mission.

In the setting of Mark 3, Jesus is gathering his twelve apostles and preparing them for their work. He is not just calling them to follow him, but also giving them real authority to help others in ways that show God’s power. The verse is part of a list describing what Jesus expected from those closest to him.

The Greek behind Mark 3:15

• The word for "power" is ἐξουσία (exousia), which often means authority or the right to act, not just strength. Here, it emphasizes that the disciples are acting with Jesus’ permission and backing, not their own ability.
• The word for "heal" is θεραπεύειν (therapeuein), which means to care for or restore health. This shows that their role was not just dramatic miracles but also compassionate help for the sick.
• The word for "devils" is δαιμόνια (daimonia), meaning evil spirits or demons. The verse points to a real struggle with spiritual forces, not just physical illness.

Why Mark 3:15 matters

• Mark 3:15 makes it clear that the disciples’ authority came directly from Jesus, not from themselves or any other source.
• The verse shows that Jesus’ mission included both physical healing and spiritual rescue, tying together care for the whole person.
• This verse sets up the rest of the Gospel, where the disciples are seen acting in Jesus’ name, and it explains why people recognized their actions as significant.
