I was discussing with someone what to say to women and decided I needed to work on this for the book on marriage. So I was preparing to look at the latest research on it and was surprised when Jesus stopped me.
He told me that I needed to show His Love towards others, whether or not I liked them and that all I do or say should be guided by The Holy Spirit so I express to the person what H e wants that person to know or how He wants that person to be served.
The latest research in this matter may be worth reading so that The Holy Spirit has things to work with but these are not really necessary if you hear The Holy Spirit as you should.
So in all you do you need to express Godís Love in what you say and how you serve them and the promise of God is that The Holy Spirit will guide you in this if you really want to hear Him (Jn 16:13)
