The thief on the cross did exactly one act: repented of his sins, trusting his salvation #ToChristAlone.
"Jesus remember me when you come into your Kingdom."
What did the thief do to be saved? He was not baptized. He did no good works. He didn't accept the pope. He didn't pray the rosary. He didn't follow the laws of Moses. He didn't attend church.
Through faith alone, by way of repentance and trust in the Lord Jesus Christ, the thief was saved.
God will never fail to bring about salvation for His elect.
