What does the Bible say about the salvation of the thief on the cross?

In Luke 23:32-43, the account of the thief on the cross illustrates the profound truth of salvation by grace alone. Despite his sinful life and the circumstances of his execution, the thief recognized Jesus' lordship and his desperate need for mercy. He asked, 'Lord, remember me when thou comest into thy kingdom.' Jesus' response, 'Verily I say unto thee, today shalt thou be with me in paradise,' confirms that salvation comes through faith in Christ alone, not through works or rituals. This moment demonstrates God's grace extending even to those at the very end of their lives.
