The New Testament tells us about the Holy Spirit as a spiritual gift. The gifts are perfections that God bestows on us so that we can resemble him: "Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows" James 1:17. The disciples had received this marvelous gift from on high at Pentecost (Acts 2:1-4), and they did not cease to praise it. The Kingdom of Heaven, the empire or domain of the excellences of God, began to manifest itself among men with this incredible miracle, as Jesus taught with wisdom: "Be perfect, therefore, as your heavenly Father is perfect" Matthew 5:48.
The arrival of the holy spirit to the disciples is commemorated as the day of the birth of the Church, and by this spirit, the disciples testified to the divinity of Jesus, and so the apostle Peter taught in his first speech this spiritual truth in the Book of Acts of the Apostles, when after descending the tongues of fire, the common and simple people of the town approached the disciples: "Exalted to the right hand of God, he has received from the Father the promised Holy Spirit and has poured out what you now see and hear," Acts 2:33.
Our Lord Jesus in a mysterious way promised to the disciples that they would not be alone after his physical departure from this world and that they would receive spiritual protection from on high. The Holy Spirit represents that transforming force, which frees men from the weaknesses of the flesh and passions, to make them enter into that new life, which is the contemplative life or eternal life, and the communion with God. But like every gift that is received from above, something must happen first, men must want to live it first. If we look for magical or instant solutions to problems, solutions of the type, "the universe provides", we will never receive anything. As Peter taught, the Holy Spirit needs our repentance before anything else, God calls us to conversion.
