The prayer of Paul: That by his power he may bring to fruition your every desire for goodness and your every deed prompted by faith. 2 Thessalonians 1:11

The Book of Acts of the Apostles relates that the Church of Thessalonica was founded during Paul's second missionary journey, and its foundation was marked by great difficulties, being the majority of its members of pagan origin. However, due to the importance of the Church, the apostle Paul dedicated two important epistles to this christian community.
And to understand Paul's language in these epistles it is important to understand that the transmission of Jesus' teachings was fundamentally oral and that the first texts of the New Testament to be written were not the gospels but Paul's own letters.
That is why many stories about Jesus caused great shock among believers, such as the resurrection and the second coming of Jesus. That is why Paul dealt with these topics, especially in his second letter to the Thessalonians, so that the new Christians would not fall into heresies, so common in those times.
But Paul as a teacher of faith did not only speak about these types of topics but also taught about the importance of the blessed life, that is why he made a small prayer in his second epistle to the Thessalonians so that the gifts received by the believers would bear their due fruit:
"We constantly pray for you, that our God may make you worthy of his calling, and that by his power he may bring to fruition your every desire for goodness and your every deed prompted by faith. We pray this so that the name of our Lord Jesus may be glorified in you, and you in him" 2 Thessalonians 1:11-12.
With this, Paul understood that the teaching was important for the new converts, but if faith is not accompanied by the fruits of the gifts, evangelization is sterile and useless. The Kingdom of God is a reality for which men have to fight every day.
