Why is the concept of whosoever important for Christians?

The declaration that 'whosoever shall call upon the name of the Lord shall be saved' underscores the inclusivity of the Gospel message. It signifies that God's grace extends beyond ethnic and cultural boundaries, inviting all individuals to respond to the call of salvation. This aspect is crucial within sovereign grace theology, as it affirms that divine mercy is not limited but available to all who genuinely seek God, irrespective of their background. Consequently, this fosters a sense of hope and assurance among believers that salvation is not predetermined but open to everyone who believes.
