Do you want to be sure you have eternal life? Then ask God for it. Here are the words you could use:
God, I admit that I am a sinner and I cannot get to heaven by my own good works. I repent of all my sins. I ask you to take them from me and lay them on Jesus Christ. I really want Christ’s perfect goodness, and I sincerely ask that you will clothe me in his goodness. Thank you for taking away my sins and for giving me eternal life.
Out of thankfulness for what you have done for me, I now dedicate myself to loving and serving you all of my life. Send your Spirit to live within me and to give me the desire and power to live for you. Amen.
If you sincerely pray this prayer, God will remove your sins and give you the perfect goodness of Christ. You will be a true believer—a new Christian—a child of God. “How great is the love the Father has lavished on us, that we should be called children of God! And that is what we are!” (1 John 3:1).
Life as a Christian will not always be easy. Sometimes you will fall into sin. But you will have a God-given desire to live right and to serve God every day. God will help you to live for him by giving you his Holy Spirit to encourage and guide you. Soon you should talk to another Christian about how to grow in your Christian life. You might try a church nearby as a starting point.
Welcome to your new life in Christ!
