What is the primary indication of receiving the Holy Spirit according to the teachings discussed?

The primary indication of receiving the Holy Spirit, particularly within the context of many Christian teachings, is often associated with speaking in tongues. This practice is seen as a significant and tangible sign that one has experienced the baptism of the Holy Spirit. It highlights the transformative power of the Spirit in the believer's life, allowing for a personal connection to God and serving as a symbol of spiritual empowerment.

While other manifestations, such as the demonstration of love, shouting praises, and performing miracles, are important elements of the Christian faith and can be seen as evidence of the Holy Spirit's work in a believer's life, they do not specifically encompass the unique and defining experience that speaking in tongues represents. Speaking in tongues is often viewed as an initial and clear sign of being filled with the Holy Spirit, as supported by scriptural accounts in the Book of Acts and other New Testament writings. This makes it the standout indicator among the options provided in relation to receiving the Holy Spirit.
