The lessons about true worship are timeless: (1) Faith obeys completely the Word of God. (2) Faith surrenders the best to God, holding nothing back. (3) Faith waits on the Lord to provide all one’s needs. But God does not provide until personal sacrifice has been made. True worship is costly. This was always so for Israel when they brought sacrifices. Those offerings were supposed to be given in faith so God would provide all the needs of each willing worshiper.
