Isaiah 54:16-17
Sent with a Powerful Promise

Isaiah 54:16-17

(16) “Behold, I have created the blacksmith who blows the coals in the fire, who brings forth an instrument for his work; and I have created the spoiler to destroy. (17) No weapon formed against you shall prosper, and every tongue which rises against you in judgment you shall condemn. This is the heritage of the servants of the Lord, and their righteousness is from Me,” says the Lord.

1. We need to understand the biblical context.
2. We need to avoid the potential pitfalls. 
3. We need to appropriate the power of the promise.
