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.’
Matthew 25:45 ESV (Entire parable: vv 31-46)
These “goats” seemed truly hurt that they were being considered to have left Jesus “high and dry” in difficult circumstances. I really do believe that He is referring to “Christians” in this verse, but that they were the ones that went to “church” every Sunday, did their religious activities and never lifted a finger to re-present Christ.
This is what I have come to believe that it truly means to “take His Name in vain” – claiming the name of Christ and acting in a manner different that He would.
Imagine how you would feel if you gave someone Power of Attorney, and all they did was make withdrawals from your account and never make any deposits!
Sin is defined as falling short or missing the mark… That is what is being described in the context of this passage – not doing what Christ would do, not treating others as you would treat Him. A Kingdom perspective of this is that there is one Commandment Jesus left us for the New Covenant: Love (agape – self-sacrificial service with no expectation of reciprocation). To not care for others is to violate that Law and, therefore, “sin” (verb).
I’m not perfect and never will be… Christianity is not about being perfect, it’s about becoming like the Perfect One in thought, word, and deed.
