It will not be good enough for us to only faith and not do good works. The thief that was crucified with Jesus could not do any good deed because he only had few hours to live. If you are to live only an hour then your faith will be enough to save us but we are live a few more days we have to do good deeds. We to do something more than faith. Love is great than faith according to 1 Cor 13:13
"And now abideth faith, hope, charity, these three; but the greatest of these is charity."
Love must not be absent from faith. Faith must be coupled with love.
1 Corinthians 13:2 And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
