God shows mercy to the elect as demonstrated in scripture where He sovereignly chooses whom He will save and has a predetermined plan for their redemption.
According to Romans 9:16, it is emphasized that 'it is not of him that willeth, nor of him that runneth, but God that showeth mercy.' This doctrine solidifies the understanding that God's mercy is not based on human will or efforts but is a divine act of grace directed at those He has chosen. From the Old Testament, we see that mercy was already promised to God’s people, as noted in Zechariah 10:6, where God declares, 'I will strengthen the house of Judah... I have mercy upon them.' This clearly indicates that God is actively involved in the lives of the elect, not merely as a passive observer but as the orchestrator of their salvation.
