Engineers tell us that the only way that metal can safely be used is after testing it. And it must exceed the testing requirements. Repeatedly. The metal to be used must be pure. And in order for it to be purified, it must go through fire. It must be melted, and molded to fit the designers purpose.
Just as metal must be molded, purified, and tested; we have to be tested before God will use us for His purposes.
