This is the first in what will likely be a series “‘Atheists’ Memes Refuted,” where we will tackle a meme posted by professing atheists and refute some of the logical fallacies, contradictions, inconsistencies, outright lies and other flaws contained in them. The goal is to correct any misconceptions about Christianity by teaching it. If unbelievers are going to reject and mock Christianity, they should at least know what they are rejecting! Ultimately, however, I’m hoping they repent.
The short response to this meme is: neither is the Christian. This gets to the heart of the Gospel. The Christian is not kind because he is trying to get into heaven. That would be salvation by works, which the Bible condemns. Scripture clearly teaches that we are saved by the grace of God alone through faith alone in Jesus Christ alone, not by any works we perform.  To believe that we contribute anything to our salvation is a damnable heresy.  So no one gets to heaven by being kind, or by any other good works.
So why is the Christian kind? In Scripture, whenever it commands Christians to be kind, it’s in light of the kindness which God has shown to us.  The cited reference quotes Jesus: “But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.” The Christian has had his heart changed, and the love of God now fills it so that he can love even his enemies and the unlovable. The same principle applies to loving other Believers as well. 
So if you’re an unbeliever and a Christian is kind to you, think of the kindness of God, which is for the purpose of leading you to repentance.
