How do we know God saves sinners?

Scripture reveals in numerous places that salvation originates from God alone and through His sovereign grace. In Mark 5, we see Jesus' encounter with the demoniac, illustrating that nobody could tame or save the possessed man except for Christ. This points to the truth that human efforts or religious practices cannot attain salvation; it is solely by God's initiative and power. God’s willingness to save, despite our sinful nature, underscores His mercy and grace. In the narrative, it is clear that the man did not come to Christ on his own; rather, Christ sought him out, showcasing God's pursuit and determination to redeem sinners. This emphasizes that no one is beyond the reach of God's saving grace.
