The definition of being a Christian is to be a follower of Jesus. Jesus loves you and wants to be in a relationship with you. So to answer the question, "How do I become a Christian?", let's look in the Bible, Romans Chapter 10 verse 9.
If you declare with your mouth, 'Jesus is Lord' and believe in your heart that God raised him from the dead, you will be saved.
It's that simple.
Your first step is to say; "Jesus, I believe you are Lord and Saviour of my life." Believe it in your heart that He died and resurrected from the dead, your sins are forgiven and your relationship with God has begun. When you trust Jesus as your Lord and Saviour, you enter into the fullness of God's love. As you start to understand God's love, you become a new person. Picture it as an adoption into a new family, one where you are loved so unconditionally you grow and become the best person you can be, not because you have to, but because you want to. God's family is huge, without walls and borders, it's limitless. Through His death on the cross, and then coming back from the dead, Jesus took all of your wrong and gave you all of His right. You have just begun the greatest journey of your life!
Prayer is talking to God as you would a close friend. He really hears you, the Holy Spirit will comfort, lead you and guide you. The Bible is God's word and is one of the primary ways He speaks to us. When we pray and read our Bible, the Word becomes alive in us. John chapter 1 reveals to us that Jesus is the Word.
