Based on 1 Corinthians 14:12-20, we explore the power of our words, drawing parallels between the Tower of Babel and the Pentecost event. Christians are called to use our words to build up the church, just as the Holy Spirit did at Pentecost. This includes speaking kindly to ourselves and others, even when it is difficult. The sermon concludes with a reminder that we are part of the priesthood of all believers and that our words have the power to bring others closer to Christ.
