Luke 13:23 asks 'Lord, are only a few saved?' — a parallel question about the scope of salvation, reflecting the same concern.

Luke 18:26 is the parallel verse — the disciples ask the exact same question 'Who then can be saved?'

Acts 16:31 provides the answer to the disciples' question: 'Believe in the Lord Jesus, and you will be saved' — faith vs human impossibility.

Romans 10:9-13 explains that salvation comes through confession and belief — directly answering how the 'impossible' becomes possible through faith.
