God saves whoever calls upon him. Whoever calls upon the name of Lord will be saved (Romans 10:13). Those who sincerely call upon the Lord are saved today. That's why today is the day of salvation.
The Bible warns about waiting for a day in the future to be saved. The danger is hardening our hearts in sin. Today if you will hear His voice, harden not your hearts (Hebrews 3:15). It's a serious matter to resist the convicting work of the Holy Spirit (John 16:7-11). That's the reason the Bible declares, Behold now is the day of salvation (2 Corinthians 6:2).
Whoever calls upon the name of the Lord will be saved. However, those who have hardened their hearts will not, even in the face of death. Life is so uncertain and death is so sure. That's why today is the day of salvation. We are not promised tomorrow.
The dying thief was saved on the day he died. Being crucified next to Jesus, he said, Lord, remember me when you come into your kingdom (Luke 23:42). Jesus said to him, Today you will be with me in paradise (Luke 23:43). There is no doubt about his salvation. The words of our Lord confirmed it. Whoever calls upon the name of the Lord will be saved.
