Philipians 1:27 Only behave in a manner worthy of the good news about the Christ...
Philipians 2:5 Keep this mental attitude in YOU that was also in Christ Jesus, ...
Galatians 6:2 Go on carrying the burdens of one another, and thus fulfill the law of the Christ
Galatians 3:26 YOU are all, in fact, sons of God through YOUR faith in Christ Jesus. 27 For all of YOU who were baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither slave nor freeman, there is neither male nor female; for YOU are all one [person] in union with Christ Jesus. 29 Moreover, if YOU belong to Christ, YOU are really Abrahams seed
I still haven't seen you post any verses from Paul which show he is against Christ... please do so because it would be wrong to accuse an innocent man.
These are not saying we have to be faithful to Jesus to be saved. Paul preaches
"faith alone" gospel.
Jesus commands us to be faithful to Him until the end, not Paul.
