The Lord said, "Come...." The Lord did not say, "Go...." So, where was the Lord? He was in the Ark!
The Lord's invitation to "Come" into the ark was to Noah and "all thy house." Yet, God extended the invitation verbally to just Noah. Noah received the invitation and then had the commission to tell everyone else: His wife, His three sons; His three sons' wives (one wife per son!). There were eight in all invited into the ark. Only one man received the message, Noah. Then Noah became the messenger to seven others.
Why did God just tell Noah? God said, "...for thee have I seen righteous before me in this generation." Which generation is God referring to? The last generation of mankind before the great flood that covered the whole earth.
Are we "this generation," that is, the last generation that will witness the second coming of the Lord? Are we telling our loved ones about his invitation to "Come" to him? Have we heard God's invitation ourselves?
