You think you need to point out other's sins? How about loving others as Christ loved you instead? If Jesus did not come to condemn (already condemned humanity) then why do you think condemning others works? You who condemn others are wasting your time. Why condemn the condemned when you can bring Light and Life to those through the same love that Jesus gave you. Read the verses below carefully, and let the words sink in. Just maybe, the understanding of being a moralist versus a Christian may come to you before you point out others "sin".
New King James Version
16 For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. 17 For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.
18 “He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God. 19 And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. 21 But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
