Those Hosea actions , and there were many other, Isaiah going bare-neked for 3 years, cooking his food over disgusting stuff, those were old testament days , we are reborn IN CHRIST and He indwells us, John 16 Jesus is giving His going away instructions and He tells us when Holy Spirit comes He will guide, speak and show, all things the old testament prophets and others were given at times and on certain people as He willed, now that same Holy Spirit is given to each of us who are born-again and Spirit Filled.
Just as Peter and John imparted to the beggar, "silver and gold have we none, but what we have we freely impart".
Our personal relationship with Him is experienced we don't just talk about Him and the Father, we experience Them, we "keep our minds stayed on Hi, and responds as he said He would, He will guide, speak, and show, words of knowledge, dreams and visions, guidance by Spirit.
"Outward form" Christians like to beat people up with their Bible "knowledge", walking in the Spirit produces "love, joy, peace, patience, kindness, goodness, faithfulness and self control".
We can beat each other with scripture or we can experience what He died to bring us,
