“For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures…” (1 Corinthians 15:3-4)
If you are a believer, you are called to pass on what you know about Jesus Christ. You need not be a fully grown Christian, let alone a theological expert, in order to bear witness of your faith. You need not have an answer to all the tough questions before you can start telling others “what you also received”. The apostle Paul mentions the most important information that people should know: that Christ died for our sins and rose again from the dead. That is the same message that Jesus commands his apostles to proclaim to all nations, accompanied by the exhortation to repent and receive forgiveness (Luke 24:46-47).
The apostles obeyed Jesus’ command and spread the Gospel all over the world. Later generations of Christians have done the same. But this work is not yet finished. There are still many people who don’t know who Jesus Christ is, or what He has done for sinful humans. It is essentially important for every single individual to believe in Jesus, but “how are they to believe in him of whom they have never heard?” (Romans 10:14)
Is there someone in your locality with whom you could share the Gospel?
