God's grace not only saves us, it sanctifies us or helps us to live a holy life. The keys in this section are realizing who you are in Christ and living like the victorious believer that you are. Some Christians don't know of their position in Christ and the potential they have in Him. Others know, but don't appropriate what they have in Christ. A key concept in these verses is to offer the parts of our bodies to God as instruments (or tools) for Him to use. The grammar and context of the text shows us that this is both a one time offering and a daily kind of committing or yielding our lives to God. We need His presence and power every day to live godly lives. Make sure to live each day as a surrendered vessel that God can use.
