We are dependent upon God's mercy for salvation

Romans 9:16 So then [it is] not of him that [b]willeth[/b], nor of him that [b]runneth[/b], but of God that showeth [b]mercy[/b].  
 9:17 For the scripture saith unto Pharaoh,[b] Even for this same purpose have I raised thee up,[/b] that I might show my power in thee, and that my name might be declared throughout all the earth.  
 9:18 Therefore hath he mercy on whom he will [have mercy], [b]and whom he will he hardeneth.[/b]
