```python
from mcp import ClientSession, StdioServerParameters
import asyncio

async def use_bible_mcp():
server_params = StdioServerParameters(
command="python",
args=["bible_server.py"],
)

async with ClientSession.from_stdio_server(server_params) as session:
# Initialize session
await session.initialize()

# Get a verse
content, _ = await session.read_resource("bible://web/JHN/3/16")
print(content)

# Use a tool
result = await session.call_tool(
"get_random_verse_tool",
{"testament": "NT"}
)
print(result.content[0].text)

if __name__ == "__main__":
asyncio.run(use_bible_mcp())
```
