The Holy Spirit is described as a divine presence that would come to the believers after Jesus' glorification, which refers to His death, resurrection, and ascension into heaven.

The Holy Spirit is seen as a source of comfort, wisdom, and strength, enabling believers to live out their faith with courage and conviction. This verse emphasizes the transformative role of the Spirit in the lives of Christians, empowering them to continue Jesus' mission of love, compassion, and truth. It also reassures believers of God's ongoing presence and support in their lives, offering hope and encouragement as they navigate the challenges of the world.
