How do we know God's mercy is for the elect?

God's mercy towards His elect is demonstrated through individual encounters as seen in Hagar's story. The angel of the Lord speaks directly to her, affirming the personal nature of God's calling. This aligns with biblical truths, such as Romans 3:11, which affirms that no one seeks God on their own. God in His sovereignty reaches out to those who are lost, ultimately directing them back to Himself. Hagar's experience highlights the grace that not only finds but also calls sinners back into His fold.
