On the first Christian Pentecost, the Holy Spirit dealt in a magnificent way with tongues. First, the Spirit appeared in the form of "tongues as of fire" (Acts 2:3). The apostles yielded their formerly silent tongues to speak in both native and foreign languages, proclaiming the prophetic Word of God (Acts 2:4ff). Their hearers used their tongues to repent and ask how to be saved (Acts 2:37).
Once the Spirit has your tongue, the battle begins. Satan accuses you of being foolish (Acts 2:13) and attacks any fears you may have. The world attempts to intimidate and silence you. This is what the apostles experienced once the Spirit took over their tongues. Nevertheless, the apostles yielded to the inspiration of the Spirit, not to the attacks of Satan and the world.
When we yield our tongues to the Spirit, the pressure to stifle the Holy Spirit and hold our tongues is so fierce that the Lord personally assures us: "Do not be afraid. Go on speaking, and do not be silenced, for I am with you" (Acts 18:9).
Today is the first day of the Pentecost Novena, nine days of prayer to prepare to receive the Holy Spirit in fullness at Pentecost. Give the Lord your mind, heart, soul, and tongue. Ask the Lord to teach you "what to say and how to speak" (Jn 12:49). Allow the Holy Spirit to control your speech in both your native tongue and in the spiritual gift of tongues.
