Those of you who are familiar with the process of refining gold know that the gold is first placed in a crucible and subjected to intense heat. The heat causes the gold to melt and its impurities to separate and come to the top, where they can be skimmed off.
This process is repeated as many times as necessary in order to increase the quality and purity of the gold. For example, 10 karat gold does not have to be heated as much or as long as 14 karat gold. Twenty-four karat gold undergoes an even more intensive refining process.
In a similar manner, God is in the process of refining His church. He wants a pure, beautiful bride upon whom He can pour out His anointing and His power. God desires to manifest Himself through His church so that each of us is able to do the things Jesus did (see John 14:12-14).
