Psalm 35:12-14
12 They repay me evil for good.
I am sick with despair.
13 Yet when they were ill, I grieved for them.
I denied myself by fasting for them,
but my prayers returned unanswered.
14 I was sad, as though they were my friends or family,
as if I were grieving for my own mother.
One of the greatest test of our hearts as Christians, is our attitude and posture towards those who do not repay us with the kindness we have extended to them.  The desire for reciprocity, or for things to be appreciated is a natural response to our kindness.  Yet the danger for us as Christians is to allow our hearts to be hardened, because people don’t appreciate it…
The test of faith, and what underlines living a Christ centered life is to repay evil with good.  It takes real faith in Christ, because naturally the response to being unappreciated with disrespect or apathy is anger.  An anger that soon turns into bitterness, where we then “clog our hearts” from the kind of unconditional love Jesus relentlessly displays to us…
To be hated without a cause seems so unreasonable that you can easily look at that person and desire for them to get what they deserve!  But the Christian has in them a spirit that desires to forgive and show compassion, though the flesh is weak (Matthew 26:41)!  This is why when we feel too weak to find compassion to overcome the lack of reciprocity from others, we must consider Jesus and who we are in Christ.
What overcomes the evil in this world is our faith.  Because only faith in Christ breaks the chain of repaying evil for evil.  Like David who was unreasonably hated, he knew that to repay evil with evil would not give him any boast in his Lord, but continue the vicious cycle of evil.  Seek Christ, and bathe your heart in how much mercy He has shown you and I for not reciprocating the love He has shown us! (1 John 5:4-5)
