There is no formula for salvation. God is the only one who can save the sinner. We have to cry to Him for His mercy because the Bible teaches that of ourselves we will never come to God on His terms.

• The LORD is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit. Psalms 34:18
  
• There is none that understandeth, there is none that seeketh after God. Romans 3:11
• It is good that a man should both hope and quietly wait for the salvation of the LORD. Lamentations 3:26
