“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.” Romans 10:9
When Jesus died, he bridged the gap that separated us from God. All you need to do is accept that, and ask Jesus into your heart.
Right now, bow your head and ask Jesus to come into your heart. Tell him you believe in him, and that you know that God raised him from the dead. And finally, ask him to forgive your sins. It is that easy!
