“Godliness is the sacred impression and workmanship of God in a man, whereby from being carnal he is made spiritual…The faculties are not new, but the qualities are; the strings are the same, but the tune is corrected.” (Chapter 2, p.12)
When we say, “He is a godly man”, or “She’s so godly”, what do we mean? Is it not that we mean we see God in them? That is, it is obvious the Holy Spirit indwells their heart and propels their words and actions.
If you profess Christ as your Lord and Savior, then you are a temple of the Holy Spirit. If you are a temple of the Holy Spirit, then you should be godly. Where does it break down, then? It is woefully obvious that we are all not all-godly all the time.
In part, I think the answer lies in the need for us to remember whose we are. 1 John 4:9 says that the love of God was revealed to us in the fact that God sent his only Son into the world so that we might live through him.
So then we can conclude: by remembering whose we are we will remember that we are to live through him, thus demonstrating who He is.
The call to godliness is the call of discipleship. Jesus said we are to deny ourselves daily, take up our cross, and follow him. Jesus demonstrated who God was. By genuinely answering the call of discipleship we get the privilege of demonstrating who God is too.
