Christian theology: The Lord—who is the Spirit—makes us more and more like him as we are changed into his glorious image. 2 Corinthians 3:18

The second letter to the Corinthians is largely a continuation of the themes set out in the first epistle, and was most likely written by the apostle after his second visit to the city.
And in the first epistle he wrote about how the holy spirit freely distributes his spiritual gifts among the converts to the Christian faith, giving some the gift of prophecy, others the gift of tongues, because the Kingdom of God is not about following a series of imperatives (the old covenant), but about living a new kind of freedom, in other words, about living the gifts received from on high. And with these words, the apostle expressed this spiritual truth: "It is one and the same Spirit who does all this; as he wishes, he gives a different gift to each person" 1 Corinthians 12:11.
And in his second epistle, the apostle continued to delve deeper into the subject and wrote about the importance of the new covenant, because the goal of spirituality is to achieve likeness to God in essence and thus inherit the spiritual gift of eternal life, the life which, once obtained, cannot be lost. Because the apostle Paul wrote that the law of Moses serves to recognize sin, but not to free man from the slavery of error.
And this spiritual freedom, in the Christian theology, is achieved only through the grace of the Holy Spirit by the faith united with a life full of mercy (compassion, gentleness, kindness) and fear of God. And in this way, those who please God are blessed and freed from that veil that hinders intelligence and prevents it from seeing the truth; through a new birth or a birth in the spirit, because the gifts are progressive, gradual, and tend towards the perfection of the human being, that is why the apostle wrote with wisdom: "So all of us who have had that veil removed can see and reflect the glory of the Lord. And the Lord—who is the Spirit—makes us more and more like him as we are changed into his glorious image" 2 Corinthians 3:18.
What the apostle Paul meant to teach with this statement is that the Kingdom of God is the conformity to Jesus. And this cannot be achieved from a position of comfort; the Holy Spirit tests those who follow Jesus, a progressive path that is difficult at first, but which later frees them from suffering and fills them with happiness.
