The purpose of My Father's House is not only to "Go into all the world and preach the gospel to all creation" but to also provide an environment that people of every background, ethnicity, and culture would feel welcomed, loved and cared for just as if you were "coming home".
Luke 15 says it like this:
20~ So he got up and went to his father.
“But while he was still a long way off, his father saw him and was filled with compassion for him; he ran to his son, threw his arms around him and kissed him.
21~ “The son said to him, ‘Father, I have sinned against heaven and against you. I am no longer worthy to be called your son.’
22~ “But the father said to his servants, ‘Quick! Bring the best robe and put it on him. Put a ring on his finger and sandals on his feet. 23~ Bring the fattened calf and kill it. Let’s have a feast and celebrate. 24~ For this son of mine was dead and is alive again; he was lost and is found.’ So they began to celebrate.
