2 Thessalonians 1:11

“And this is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ—to God’s glory and praise.”

Echoes Paul's prayer for spiritual growth and worthiness.

“For this reason, since the day we heard about you, we have not stopped praying for you. We continually ask God to fill you with the knowledge of his will through all the wisdom and understanding that the Spirit gives, so that you may live a life worthy of the Lord and please him in every way: bearing fruit in every good work, growing in the knowledge of God, being strengthened with all power according to his glorious might so that you may have great endurance and patience, and giving joyful thanks to the Father, who has qualified you to share in the inheritance of his holy people in the kingdom of light.”

Similar language about being worthy, God's will, and being strengthened.

“All this is evidence that God’s judgment is right, and as a result you will be counted worthy of his kingdom, for which you are suffering.”

Connects to the idea of being counted worthy of God's kingdom.

“I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people,”

Relates to the calling of God and his purpose.

“But we ought always to thank God for you, brothers and sisters loved by the Lord, because God chose you as firstfruits to be saved through the sanctifying work of the Spirit and through belief in the truth. He called you to this through our gospel, that you might share in the glory of our Lord Jesus Christ.”

Discusses God's calling and the attainment of glory.
