What does the Bible say about when a sinner is saved?

The Bible presents salvation in various tenses—past, present, and future—indicating that God has indeed saved and is saving His people. According to Isaiah 45:17, ‘But Israel shall be saved in the Lord with an everlasting salvation.’ This highlights that God's elect, or true Israel, will undoubtedly be saved. The concept of salvation is comprehensive, involving deliverance from sin, Satan, and the present evil world. The assurance is that not one member of His elect will be ashamed or left behind, for God's will to save is the sure foundation of our salvation.
