Our bodies, given as a living sacrifice. In verse 2, it says, that we might be transformed. Just as Christ poured out his life for us, we are to give up our lives to him. It is a process, but the word transformed is from the word, metamorphosis. Think of the caterpillar transformed into the beautiful butterfly. Only God can do this in our lives, through the power of the Holy Spirit. Some believers process is faster or slower than others, but in the end, we will be transformed. Thank you, Jesus.
