As quoted below, Jesus taught us not to judge others and those who claim to be Christian should follow these words.
"For all those who exalt themselves will be humbled, and those who humble themselves will be exalted."
Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?
Some Christians honestly believe that it is their duty to run around judging people, digging up dirt and spreading rumors. They think for them there will be some reward. But this is what Jesus says to these people:
The Final Judgment
31 “When the Son of Man comes in his glory, and all the angels with him, then he will sit on his glorious throne.32 Before him will be gathered all the nations, and he will separate people one from another as a shepherd separates the sheep from the goats. 33 And he will place the sheep on his right, but the goats on the left. 34 Then the King will say to those on his right, ‘Come, you who are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world. 35 For I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, 36 I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.’ 37 Then the righteous will answer him, saying, ‘Lord, when did we see you hungry and feed you, or thirsty and give you drink? 38 And when did we see you a stranger and welcome you, or naked and clothe you? 39 And when did we see you sick or in prison and visit you?’ 40 And the King will answer them, ‘Truly, I say to you, as you did it to one of the least of these my brothers, you did it to me.’
41 “Then he will say to those on his left, ‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels. 42 For I was hungry and you gave me no food, I was thirsty and you gave me no drink, 43 I was a stranger and you did not welcome me, naked and you did not clothe me, sick and in prison and you did not visit me.’ 44 Then they also will answer, saying, ‘Lord, when did we see you hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to you?’ 45 Then he will answer them, saying, ‘Truly, I say to you, as you did not do it to one of the least of these, you did not do it to me.’
Did you notice that those who were welcomed by Jesus were wondering why they were welcomed and those who were not welcomed thought that they should have been. Evangelist often teach that if you are saved then you know it, but what Jesus teaches here is the complete opposite.
If you are a Christian as you claim, you should be following the advice of your savior and not be running around judging people. According to Jesus, if you are saved, you are running around feeding the hungry, quenching the thirst of those thirsty and clothing the naked. Many hunger for love and acceptance and thirst for justice and some feel shamed as if they were naked. You are supposed to be helping them, not judging them. But if you yourself are hungry for attention and love and thirst for justice and maybe ashamed, then you will in your own defense judge other people. Seek salvation for yourself rather than railing judgement onto others. We know who you are.
