Jesus only speaks in the hearts of believers. If you are not saved and want to become a Christian, then ask your parents or a Christian adult you know to explain how.
Matthew 28:5-6 says: The angel said to the women, “Do not be afraid. I know who you are looking for Jesus, who was crucified. He is not here, He is Risen, just as he said he would! Come and see the place where He was lying!”
That verse above is the reason why we celebrate Easter. To celebrate that Jesus is not dead, but He is surely alive! Jesus died and rose again to save us from our sins. We know that He was risen because of two reasons: 1) The Bible tells us that He rose (and the Bible, since it is God’s Word, is our proof that Jesus and God are real) and, 2) Because many people saw Him after He rose from the dead. In fact, according to 1 Corinthians 15: 5-6, 500 people saw Him after the Resurrection.
I don’t know about you, but I think that all believers at some point in life question whether Jesus is real. At least I know that I did. I was sitting in church one Sunday morning, and my pastor said that Jesus loves me like crazy. Right after he said that, Jesus spoke to my heart and said that He is surely real. If I believe that there is wind, although I cannot see it, then why would I not believe in a God that I cannot see, but who speaks in my heart?
But Jesus only speaks in the hearts of believers. If you are not saved and want to become a Christian, then ask your parents or a Christian adult you know to explain how. They will pray with you. You can also say this simple little prayer, if you believe that Jesus is God and died and rose again: “Dear Jesus, I know I am a sinner, I want you to live in my heart, please forgive me of my sins, so that when I die I will go to Heaven and live with you forever and ever. In Jesus' name I pray, Amen.”
When you believe and pray that prayer, God welcomes you into His family and you start a new Christian life. If you go to church, speak to your pastor about you accepting Jesus. Remember to pray, and read your Bible. As my mom says, that is the only way you will be sure that our God is real.
