Ezekiel 20:40
For in mine holy mountain, in the mountain of the height of Israel, saith the Lord GOD, there shall all the house of Israel, all of them in the land, serve me: there will I accept them, and there will I require your offerings, and the firstfruits of your oblations, with all your holy things.
Ezekiel 20:40 stands within the Lord's warnings to His people, warnings they failed to heed despite the great things He had done for them and the mercy they had received. That same warning applies to God's people in Battle Creek, who with all their great light have neglected His work and have not heeded His warnings. The verse is a call for all to serve God and to honor Him. It declares that God will not be trifled with, but will punish disobedience.
