Chapters 1 to 3 = The key word is Wealth
Chapter 4 to 6 = The key word is Walk
Firstly, when we are called by Grace, we as Christian must walk in Unity;
Secondly, since we are raised from the dead, we must walk in Purity;
Thirdly, and because we have been reconciled with God, we must therefore walk in Harmony;
Finally, because Christ has victory over Satan, we can hence walk in Victory.
