How do we know that God calls us instead of inviting us?

In the biblical narrative, the notion of God primarily calling rather than inviting human beings is crucial when discussing salvation and divine grace. The call of God is not merely a polite request; it is a compelling command that resonates deeply with the soul's needs. Passages that depict God's interactions with humanity, such as in Psalm 27:8, show that the Lord calls those who cry out in their hearts for help and fulfillment. Therefore, God's call acts as a gracious response to our spiritual hunger and thirst, making it a divine necessity rather than an optional invitation. This distinction underscores the Reformed understanding of God's sovereign grace in salvation, where His call effectively moves the heart to respond.
