Of course works are ongoing. Subsequent does not imply that they are not ongoing, only that they follow having been justified/accounted as righteous/saved through faith. Good works which are produced out of faith do not precede salvation through faith, but follow. (Ephesians 2:8-10)
We have not been saved from the PRESENCE of sin (glorification) till the end, but believers have been saved from the PENALTY of sin (justification) before the end. (Romans 5:1)
There are three tenses to salvation. 1. We have been saved from the PENALTY of sin (justification) 2. We are being saved from the POWER of sin (ongoing sanctification) 3. We will be saved from the PRESENCE of sin (glorification).
Sounds like an oxymoron.
I grew up in the Roman Catholic church.
By the words of Jesus here are those who are saved. (John 3:15,16,18; 5:24; 6:40,47; 11:25,26) In 1 John 5:11-13, we read -And this is the testimony: that God has given us eternal life, and this life is in His Son. 12 He who has the Son has life; he who does not have the Son of God does not have life. 13 These things I have written to you who
believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.
Praise God!
