This is the most important decision you will ever make in your life. Where will you spend eternity?

Jesus is the Son of God. He was sent by God to die on the cross to take the sins of the world, for all time, upon Himself. In doing this, He made it possible for our sins to be forgiven. He paid the price for our sins. Then He was resurrected so that we could escape death and hell, and spend eternity in the Kingdom of Heaven with the Lord God. He made that possible for all of us.
 
John 3:16
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
 
Romans 6:23
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

We cannot save ourselves. No amount of good deeds will ever get you into Heaven. You cannot talk your way there. No bribes, no promises, no other person can get you in. We are all sinners. All of us. We need the pardon that Jesus purchased for us. It doesn't matter how good or how bad of a person you are. Jesus died to save all of us! He can and will forgive your sins and save you!
 
Ephesians 2:8-9
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.

There is only one way to receive salvation.
 
John 14:6
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

You must believe that Jesus died for you, to take away your sins. That He was raised from the dead, so that you could be granted eternal life through His sacrifice for you.

God sent Jesus to die for us, because we had no way of saving ourselves. Only the blood Jesus shed will take away your sins. Pray. Admit your sins to God. Ask God to forgive you. Ask Jesus to come into your heart, and be your Savior. Believe that He died so that you could be forgiven, and receive the beautiful gift of eternal life that He bought for you with His death and resurrection. Believe these things with all your heart, and accept Him into your life. Repent, turn away from your sins.

Romans 10:9
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.

If you pray these things, believe them with all your heart, and turn from your sins, then you will be saved!

So, what now?

You are a new creation in Christ Jesus! You have a new life, a new start. Give your life to Him completely. Read the Bible. Make it the rulebook for your life. Try to find a church that teaches the literal truth of the Bible, God's Holy Word. Get baptized. Seek out other believers and join them in fellowship and in the worship of God. Resist sin and the temptations to sin. He will give you the strength to turn from those sins!

And spread the Word to others. Share the good news that Jesus Christ brought to us with everyone you can.
