Am I the good witness of the Lord?

Isaiah 44:1-8
This what the Lord says -- he who made you who formed you in the womb, and who will help you.
I will pour water on the thirsty land and streams on the dr groud; I will pour out my Spirit on your offspring, and my blesing on your descendants.
This is the Lord says -- Israel's king and Redeemer, the Lord Almighty: I am the first and I am the last; apart from me there is no God. You are my witnesses. Is there any God besides me? No, there is no other Rock; I know not one.
Why?
These chapters continue the themes that run through the whole section : Israel as God's servant, the onject of his love.
Radicule of the lifeless no-gods that humans worship.
The Lord has chosen us when we are in the wormb. We even didn't be born.
The Holy Spirit will pour out on his servant, then has the ability to know the Lord and do the witness of the Lord. All Christians are His witness.
There is not other really God beside the Lord, He is the first and the last. God is  forever lasting God.
How?
Do not afraid the Lord's blessing and help will pour out on me, He will help me, even I don't know what will be in the future. He is my God, my shepher and my king. Am I the good witness of the Lord?
