Radical speaks to the origin or root of something but not to the extreme version.
It’s reasonable to be radical because:
- it’s all about God 
- of His mercies toward us 
- God gives the ability to do the “unreasonable” 
- God is pleased with such sacrifices 
- Giving your all to God is logical service (worship) 
Living sacrifices
- offer themselves voluntarily 
- offer up themselves daily 
- can crawl off the altar
