What does the Bible say about God's discriminating grace?

In Luke 10:21-22, Jesus expresses the sovereignty of God in salvation, highlighting that it is God who reveals His truths. The Lord thanks the Father for concealing the gospel from the wise and revealing it to 'babes', underscoring the doctrine of discriminating grace. This reflects God's sovereign purpose in electing some for salvation while leaving others in their sin. Hence, it is not the will of man but God's divine choice that determines who receives the grace of salvation. This principle is foundational to understanding the nature of God's grace and purpose in the lives of believers.
