One who prays fervently for others, helps out however they can and has empathy for a fellow sufferer with a breaking heart is a good Christian?   In Romans (2:11), "For there is no respect of persons with God." (2:14) "For when the Gentiles, which have not the law (*of God) do by nature the things contained in the law are a law unto themselves."

    All people (Christians and non-Christians) have a knowledge of God's law, for He "shall put My spirit in you." (Ezekiel 37:14)  People will break God's law but then it's their own law.  No matter how good we are and/or how good our words are, those who face God on their own merits will be guilty!  Only through repentance and faith in Jesus Christ will God welcome those to His Home in Heaven for eternity.

   At the final judgment, Jesus will be there for us and all who have repented and have  received Him in faith as their Savior will be spared from tribulation and welcomed Home.
