Now these three remain: faith, hope and love. But the greatest of these is love. 1 Corinthians 13:13
I know it's very hard to remember that love will triumph all when we are in the midst of bitterness, resentment, prejudice, etc. But Love will remain. Thousands of years ago, Christ was unjustly tried and mocked by the Romans and fellow Jews. He was nailed to the cross - and crucifixion was one of the worst ways to die.
Yet, the awe of it all was that Jesus loved so much that he offered forgiveness right there on the spot to those who persecuted him. He asked God to forgive them. His love was so amazing that it surpassed all the powers of hatred.
When in your life, you feel unloved remember that Jesus came and taught about how to love. But more so, he didn't just tech - he completely lived out that message. He was human just like us. And so when you are in that place in your life, remember his life and you will find peace and calm -- it will make you aware that love will always remain.
