You’re not alone. Breathe a sigh of relief. This is not God sending you out on your own to preach the gospel all over the world and saying, “Good luck!” No, He has promised to send the Holy Spirit to help you be an effective witness for Jesus Christ. Jesus said, “But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you.” (John 14:26). What does it mean that the Holy Spirit is your Helper to be a witness for Jesus?
Imagine a sailboat. You set out to sail across the sea to another country. You buy your boat, map out your general direction, and take off from land. But you have to trust that the wind is going to come, fill your sails, and carry your boat across the sea. That’s a lot like witnessing. You have heard the command from Jesus to go and make disciples of all nations. You can set your heart to be obedient to Him and prepare to tell others about Jesus, but it’s the Holy Spirit who is going to fill your sails and do all the work. And He promises to send the wind to you. Jesus said, “but you will receive power when the Holy Spirit has come upon you; and you shall be My witnesses” (Acts 1:8).
"But sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence." 1 Peter 3:15
"How then will they call on Him in whom they have not believed? How will they believe in Him whom they have not heard? And how will they hear without a preacher?" Romans 10:14
And it doesn’t matter if you don’t have a naturally “bold” personality. Sometimes we think that only the really confident or outgoing people are good at sharing the gospel. But the power of the Holy Spirit is available for everyone—not just the extroverts. Think of the sailboat illustration: it doesn’t matter if the sailboat is big, small, brown, colorful, long, or short. As long as it has sails, the wind can carry it. It’s the same with the Holy Spirit: He can take whatever personality you have and use it to draw fame and glory to Jesus. The sails of your boat are just your willingness to tell others about Jesus. The Holy Spirit will give you the power and the right words. Would you like to witness with the help of the Holy Spirit? Ask God right now to fill you with His Spirit and give you opportunities to witness. Jesus said, “How much more will your Heavenly Father give the Holy Spirit to those who ask Him!” (Luke 11:13). As you and the Holy Spirit work together, you will see people believe in Jesus and receive eternal life.
"For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek." Romans 1:16
