Here's why. A Syrian Christian flees her country because of war and all that comes out your heart and mouth is condemnation. Search your heart; the love of God is not in it.
What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him? If a brother or sister be naked, and destitute of daily food, And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit? Even so faith, if it hath not works, is dead, being alone. James 2:14-17
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that does the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity. Matthew 7:21-23
