In the context of spiritual gifts, speaking in tongues is a personal experience that enhances one's own spiritual life. It is a form of prayer or praise that connects the individual directly with God, often in a language unknown to the speaker. While this can be a powerful personal experience, it primarily benefits the individual unless interpreted for the congregation.
On the other hand, prophecy is a gift that serves the broader church community. It involves speaking forth God's truth and guidance, often providing insight, encouragement, and correction that can uplift and unify the church body. By highlighting prophecy, this verse underscores the value of gifts that promote communal growth and understanding within the church. It encourages believers to prioritize gifts that build up others, fostering a spirit of unity and shared faith. This reflects the broader biblical theme of love and service to one another, emphasizing that spiritual gifts are given not just for personal benefit but for the edification of the entire church.
