Putting on the New Man

What I would like to do at this time is to look 1st of all, at what it means, to be renewed in the spirit of your mind, as a Christian. And then 2nd, to look at what it means to put on the new man which was created according to God, in true righteousness and holiness. We have a responsibility to ourselves, first, in the sight of God, in this regard, before we can rightly take up the particular responsibilities that we have towards each other. May the Lord help us by means of this study to understand better what it means to be righteous and holy people, for this is what God has called us to.
