How do we know that grace is sovereign?

Sovereign grace refers to the truth that God's grace is freely given without any conditions based on human actions or merits. This concept is rooted in the understanding that salvation is entirely the work of God. Paul writes, 'But when it pleased God, who separated me from my mother's womb and called me through His grace' (Galatians 1:15). This illustrates that God's grace is not a response to anything in the individual but is solely rooted in His divine will and purpose. As Romans 9:15 states, 'For He says to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.' Hence, understanding grace as sovereign reassures believers of their security in Christ, as it depends not on their fidelity but on God's perfect promises.
