What role does God's mercy play in salvation?

In Hebrews 8, we see God's remarkable mercy described as the means by which He makes a new covenant with His people. This is a covenant in which God's laws are placed in our hearts, and His mercy erases our iniquities. This reflects Romans 9:15, where God declares, 'I will have mercy on whom I will have mercy.' Only by His mercy can we come to know Him and be saved, as it is God who, in His threefold nature, draws men to repentance and faith in Christ. Without this divine grace, we remain in our natural, sinful state, incapable of saving ourselves.
