Thanks for your question.
Romans 10:9,10 is a great text about how one is
saved. It is true that the only things mentioned there are faith and confession. But it is
a mistake to think anything is not important because it isn't mentioned in a single text.
This verse doesn't mention repentance either. Would that mean repentance is not essential
for salvation? Think of Acts 2:38 as a comparison. Peter told those asking what to do to
repent and be baptized into the name of Jesus Christ for the remission of sins and you
will receive the gift of the Holy Spirit. Notice, neither faith or confession are
mentioned in this verse. One has to take all of Scripture on any subject to have the full
truth. It would certainly be a mistake to read Acts 2:38 and conclude faith or confession
are not necessary for salvation.
Jesus said one had to be born again of the water and
the Spirit to enter the kingdom, (John 3:5). Paul wrote in Ephesians 2:8,9 that it is by
grace we are saved though faith. All these verses are true. None contradict the others. We
must accept and follow all of them.
I trust this is helpful.
