How do we know that God's mercy is essential for salvation?

God's mercy is foundational to the concept of salvation within sovereign grace theology. As highlighted in 1 Timothy 1:16, Paul obtained mercy as a pattern for others, showing that even the most notorious sinner can be saved. This underscores that mercy is not something we can earn or deserve; it is a gracious and unmerited gift from God. Without His mercy, humanity remains in a state of condemnation, for our best efforts do not meet God's holiness. Thus, it is through accepting His mercy revealed in Christ that we find salvation.
