Established?
In  2 Kings 24, Jehoiachin whose means established by God, misused his God  given opportunity by following the way of evil. His name also means  prepared by God, to be stable, fortified or fixed. However, He did not  allow God to prepare Him and be used for God's purposes. 
 
Are  you happy? are you contented? are you sometimes envious? are you where  you should be on the way to where you are going? are you complete in  God?
 
To be established is to be resolute, unshaken, unmovable in your stand for Christ and for God. If  Daniel had not been not established, he would have turned his back on  God when he was thrown into the lions den for his faithful service for  God. He could have asked `which kind of God would allow His own faithful  to be arrested? convicted? and on the way to being thrown to the lions  as a festive dinner to hungry carnivorous animals? He could have  concluded that if this God He was serving was powerless to even deliver  him from these unfaithful colleagues in the ruling cabinet; he was not  going to serve God anymore. Thank God Daniel did not doubt or waver in  his faith, otherwise, he would have served as a festive delicacy to the  lions.
 
You need to be established to be preserved to the end without reproach or shame.
who  will also keep you stedfast to the very End, so that you will be free  from reproach on the day of our Lord Jesus Christ. WNT - 1 Corinthians 1:8
to the end he may establish your hearts blameless in holiness before our God and Father, at the coming of our Lord Jesus with all his saints. - 1 Thessalonians 3:13
God  will establish you through His comfort and faithfulness as you yield to  Him and allow Him work in you and through you. Remember, God who  has  kept you from the day you were born to this time and will yet keep you.  Stay in faith, knowing that He will yet keep you and make ways for you.
Now to him who is able to establish  you according to my Good News and the preaching of Jesus Christ,  according to the revelation of the mystery which has been kept secret  through long ages, ..to the only wise God, through Jesus Christ, to whom  be the glory forever! Amen. -Romans 16:24,26
