What matters most to God is that all we do is about HIM. God brought the children of Israel to the promise land so that they can fulfill His plan on earth as God's people. So, every matter that will concern God must consider God to the the ultimate reason for whatsoever we find ourselves doing. It is about reminding ourselves that we need to be reminded that what we do must be about the right thing, which can also be interpreted as " Christ in me/you, the hope of glory" - Colossians 1:27. Many times, we can make our plans about God and go all out, loosing sleeping, being restless over the plans we have devised but like the message to the church of Ephesus in, Revelation 2: 1-7, we can labour in patience, even persevere in hardship but we must not miss out the most important thing, which is to make ALL in our lives about God.
This is what Ruth did by choosing to neglect her life in Moab and deciding to make the rest of her life about the God of Naomi. This decision will in turn become the break through she needed to be restored to God's original purpose for her life. This decision enables God to restore us to His original plan for our lives.
