The character of the new man, is one that is in lines with the Lords. His heart needs to be close to the heart of God and his mind needs to be in praise of the Father. It's interesting to look at the contrast between the man of the world and the man of God.
To talk about the Christian home is a matter that many don't take to heart. The last part of this chapter is filled with what we need to be and what we should desire to become. I love the final part where it says, "But he who does wrong will be repaid for what he has done, and there is no partiality." I will answer for what I've done. It's a good reminder to see what we do before we do them.
For an application I will asked the Lord what I need to do this week and how to become that thing.
