"Do not say that faith in Christ alone can save you, for this is not possible if you do not attain love for Him, which is demonstrated by deeds. As for mere faith: 'The demons also believe and tremble'(James 2:19)." St. Maximus the Confessor

There is no other Savior but Jesus Christ. Faith in him brings us salvation. But this faith involves doing the will of the Father. Jesus himself indicated this when he said there will be those who acknowledge him as Lord but did not do the will of the Father. What is this will? That we love others. Faith without love is like a friend only in name and not in action. Faith is the power that turns on the computer, but you need the password to activate it. It is a both/and reality.
