Matthew 9: 27-30a
When Jesus departed from there, two blind men followed Him, crying out and saying, "Son of David, have mercy on us!"
And when He had come into the house, the blind men came to Him. And Jesus said to them, "Do you believe that I am able to do this?"
They said to Him, "Yes, Lord."
Then He touched their eyes, saying, "According to your faith let it be done to you." And their eyes were opened.
These two men needed Jesus to heal them, to take care of them. They asked Him to have mercy on them. The only thing Jesus needed to know before He healed them: did they believe that He could heal them. The answer: Yes. So because they believed in Him, and had faith, they were healed.
Salvation is the same way. We have to ask God for mercy and forgiveness, and believe that Jesus is the way to receive it. If we believe in Jesus (having faith) we'll be healed (saved).
How do you do that? With this prayer:
"Lord, I know that I am a sinner, but I also know that Jesus died for my sins, so that I can be with You for forever. I pray that You will forgive me for my sins, not because I'm worthy of it, but because Jesus died for me. I ask You to come into my life, and heal me from my sinful living. Thank You for this gift of salvation, Lord. In Jesus' Name, Amen."
That's the salvation prayer (or a form of it). If you believe it, and you pray it, God will forgive you for your sins, because Jesus' blood paid our debt to Him. Just because you said this prayer doesn't mean that you'll have an easy, sinless life. It just means that when this life is over, your next one is better.
