ODDLY ENOUGH, THIS PASSAGE SEEMS TO EQUATE LOVING GOD TO ACTUALLY DOING WHAT HE SAYS!
"And the foreigners who join themselves to YHVH, to minister to him,
to love the name of YHVH, and to be his servants,
everyone who keeps the Sabbath and does not profane it,
and holds fast my covenant— these I will bring to my holy mountain,
and make them joyful in my house of prayer;
their burnt offerings and their sacrifices will be accepted on my altar;
for my house shall be called a house of prayer for all peoples."
Isaiah 56:6-7 (ESV2011, MBM)
