To be saved believe that Jesus died, was buried and raised the third day for your justification.
1 Corinthians 15:3-4 (AKJV)
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; 4 and that he was buried, and that he rose again the third day according to the scriptures:
Romans 3:24 (AKJV)
24 being justified freely by his grace through the redemption that is in Christ Jesus:
Romans 5:1 (AKJV)
5 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:
Ephesians 1:7 (AKJV)
7 in whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace;
Ephesians 2:8-9 (AKJV)
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.
