If somebody were to offer you a Mercedes Benz car for free, you would most likely say yes. Why? Well, for one, it's a nice car. But better yet - it won't cost you anything! Well, here you will find something much better than any car that also doesn't cost anything. That something is salvation and eternal life. That means that you will be able to go to Heaven after you die to live for the rest of eternity. All you do is pray to God something like this:

Dear God,
I know I've messed up and sinned against you, but I'm repenting and I want your forgiveness. I know your son went on the cross to pay for my sins and I want to accept him into my heart. Guide my paths from now on, and help me to grow in my faith.
In Jesus's name,
Amen!

If you just prayed that, congratulations! Now, if you don't have one already, I suggest you go get yourself a bible. If you're a teen, you should maybe get one that looks cool in a version you can clearly understand so it keeps you captivated. Get plugged into a church or youth group where you can grow closer to God.
