Matthew 7:6 (b) This represents the precious truths of GOD and the beautiful revelations of His Word which should not be presented to militant atheists nor to hostile, ungodly men.
Matthew 13:45 (b) This gem is a type of the church which is hidden in the world, and sought out by our Lord JESUS CHRIST who paid the great price at Calvary to purchase us with His own Blood.
Revelation 21:21 (b) These gems are probably descriptive of the life experience of the twelve patriarchs. Their names appear on these twelve pearls. (See vvs 12,21). In the Old Testament ( Exodus 28:21), the names of these same men were on stones. Having lived their lives, and the twelve tribes having gone through the terrible experiences of the centuries, these stones were changed into pearls, for pearls are the product of long suffering. The tiny stone in the shell becomes covered with the pearl substance by the oyster because of suffering.
