"A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another." (John 13:34-35)
Jesus calls us to love others as He has loved us. Of course, doing this without error is impossible. Yet we are to try our best.
Love goes further than praying for your brothers and sisters in Christ.
"Ye have heard that it hath been said, Thou should love thy neighbor, and hate thine enemy." (Matthew 5:43)
That is typical human nature. We love those who love us, of course, because we get the love! We as humans are naturally selfish. It is encoded into our sin nature.
"For if ye love them which love you, what reward have ye? Do not even the publicans the same?" (Matthew 5:46)
Sure, you'll have a reward for loving those who love you, but Christ is asking more of us. He tells us this:
"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." (Matthew 5:44)
Ouch. Now that is an act of kind love. This is Christ's definition of 'true love.' It is not some 'girlfriend' mushy-gushy stuff. Real love doesn't expect in return. Real love isn't always 'feel-good' either.
"As many as I love, I rebuke and chasten: be zealous therefore, and repent." (Revelation 3:19)
Out of His divine and limitless love, He rebukes us, so we may become stronger in Him. Repent of your sins and turn your eyes upon Him.
God bless you.
