Luke: 12. 4-5 "I tell you, my friends, do not be afraid of those who kill the body and after that can do no more. But I will show you whom you should fear: Fear him who, after your body has been killed, has authority to throw you into hell. Yes, I tell you, fear him.
Ask God to give you voice to speak properly
1 Corinthians: 2. 4. My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit's power, 5. so that your faith might not rest on human wisdom, but on God's power.
Jeremiah: 29. 11. For I know the plans I have for you," declares the Lord, "plans to prosper you and not to harm you, plans to give you hope and a future. 12. Then you will call on me and come and pray to me, and I will listen to you. 13. You will seek me and find me when you seek me with all your heart.
Acts: 2. 1. When the day of Pentecost came, they were all together in one place. 2. Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. 3. They saw what seemed to be tongues of fire that separated and came to rest on each of them. 4. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them. 5. Now there were staying in Jerusalem God-fearing Jews from every nation under heaven. 6. When they heard this sound, a crowd came together in bewilderment, because each one heard their own language being spoken. 7. Utterly amazed, they asked: "Aren't all these who are speaking Galileans? 8. Then how is it that each of us hears them in our native language? 9. Parthians, Medes and Elamites; residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10. Phrygia and Pamphylia, Egypt and the parts of Libya near Cyrene; visitors from Rome 11. (both Jews and converts to Judaism); Cretans and Arabs—we hear them declaring the wonders of God in our own tongues!" 12. Amazed and perplexed, they asked one another, "What does this mean?" 13. Some, however, made fun of them and said, "They have had too much wine." 14. Then Peter stood up with the Eleven, raised his voice and addressed the crowd: "Fellow Jews and all of you who live in Jerusalem, let me explain this to you; listen carefully to what I say. 15. These people are not drunk, as you suppose. It's only nine in the morning! 16. No, this is what was spoken by the prophet Joel: 17. "'In the last days, God says, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your young men will see visions, your old men will dream dreams. 18. Even on my servants, both men and women, I will pour out my Spirit in those days, and they will prophesy. 19. I will show wonders in the heavens above and signs on the earth below, blood and fire and billows of smoke. 20. The sun will be turned to darkness and the moon to blood before the coming of the great and glorious day of the Lord. 21. And everyone who calls on the name of the Lord will be saved.'
