My honest prayer is that you are genuinely seeking the answer to that question!!!
Jesus told Niccodemus in John 3:3 "...you must be born again". He went on the explain what I quoted above in John 3:14-16
" 14 Just as Moses lifted up the snake in the wilderness, so the Son of Man must be lifted up,
15 that everyone who believes may have eternal life in him.”
16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
Titus 3:5 elaborates he saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit,
John 1:12-13 further explains 12 Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God— 13children born not of natural descent, nor of human decision or a husband’s will, but born of God.
