Now I would remind you, brothers, of the gospel I preached to you, which you received, in which you stand, and by which you are being saved, if you hold fast to the word I preached to you—unless you believed in vain.
For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, and that he appeared to Cephas, then to the twelve. Then he appeared to more than five hundred brothers at one time, most of whom are still alive, though some have fallen asleep. Then he appeared to James, then to all the apostles. Last of all, as to one untimely born, he appeared also to me.
(1 Corinthians 15:1-8 ESV)
Place your faith in Jesus Christ, God in the flesh, by devoting your life unreservedly to Him and repenting of (turning away from) your sins. Get baptized in water, symbolizing the washing away of your sins by Christ. You don’t have to even go to a church building for this! You can get baptized in a bathtub or a lake! Any born-again Christian believer has the right from Jesus to baptize you. Seek to serve Him with everything you have- He deserves nothing less. Don’t expect it to be easy- but do most certainly expect it to be worth it. Saying a few words in a prayer and then moving on with your life as usual is not the way to salvation. Jesus, who is God and Creator, demands your all.
Does this mean you have to achieve sinless perfection in order to be saved? No! By no means! But God knows our hearts. God knows the difference between those who are truthfully seeking to serve Him with their lives, and those whose faith is not genuine.
Now go into the world and tell others.
