What do Pentecostals commonly see as evidence of the Holy Spirit's presence?

Pentecostals commonly see speaking in tongues as a primary evidence of the Holy Spirit's presence. This belief is rooted in their interpretation of the events described in the Book of Acts, particularly Pentecost, where the apostles began to speak in various languages as the Holy Spirit empowered them. For Pentecostals, the ability to speak in tongues, or glossolalia, is not only a sign of the Holy Spirit’s indwelling but also an essential aspect of experiencing a deeper relationship with God. This practice reflects their emphasis on personal spiritual experiences and the belief in active and direct encounters with the Holy Spirit.

The other choices, while significant in various Christian practices and denominations, do not hold the same level of importance within Pentecostalism regarding the manifestation of the Holy Spirit. Liturgical prayer, infant baptism, and formalized rituals may be observed in many Christian traditions but are not specifically viewed as evidence of the Holy Spirit's presence in the same way that speaking in tongues is within the Pentecostal context.
