Isaiah made an interesting prophecy (Is. 49:1-3 NKJV)

“Listen, O coastlands, to Me,
And take heed, you peoples from afar!
The LORD has called Me from the womb;
From the matrix of My mother He has made mention of My name.
And He has made My mouth like a sharp sword;
In the shadow of His hand He has hidden Me,
And made Me a polished shaft;
In His quiver He has hidden Me.”
“And He said to me,
‘You are My servant, O Israel,
In whom I will be glorified.’

There are four interesting points here:

You are called to purpose.

Isaiah was called to a purpose from his mother’s womb - He was named before birth. Isaiah means Jehovah and deliverer. His purpose, or calling, was defined before birth. The word purpose (1 Tim. 1:9) comes Thesis implies authorship. God creates us before birth for a purpose and calling. That purpose will be completed. It is already completed in te heavenlies. We are called to complete it on Earth. This petition is in the Model Prayer as given by Christ: May your purpose be done on earth as it is already done in heaven.

The spoken word - God’s purpose - has power and authority.

The verse says that Isaiah’s word is spoken as a sharp sword. It has both power and authority to accomplish God’s purpose. The Greek refers to this as the rhema word, a word that acomplishes that for which it is spoken.

The rhema word is protected and hidden.

This passage states that this word, spoken with power and authority, is hidden to protect it from the Enemy.

God’s purpose is to glorify His name.

The whole agenda has the purpose of glorifying God’s name.
