As the saying goes on, "If you look for the bad in people expecting to find it,you surely will." Is it hard to look for good in the bad? Yes. But there is always a great reward. It is worth the effort.
If you have the spiritual maturity and the emotional fortitude, you can search for the good in your enemy. Seek the good and you will find the good. While on earth, Christ experienced hurt and pain from those who made themselves His enemies. But still He chose to love them. The entire time He walked with Judas, He knew that Judas would betray Him. But there is no any indication in scripture that He treated Judas badly. When we seek to have the attitude of Christ toward others we demonstrate Jesus' example of compassion to others. It is a choice to seek the good in others. A choice that is challenging and unpopular. But we aren't called to be popular. We are called to effect change.
Our behavior towards others should bring out the best in others. Matthew 5:13 asks the question, "but if the salt loses its flavor, how shall it be seasoned?" We are the salt of the earth, intended to improve the tastes of life. Our attitudes should never leave a bad taste in anyone's mouth no matter how much they hurt us. David demonstrates how to love our enemy by seeking good in 2 Samuel 1:17-27. Even though Saul made David's life miserable and even tried to kill him, David chose not to speak evil of Saul. Instead, David used his musical talent to write and perform a beautiful song for Saul's funeral. David chose to see the good in Saul. He choose to see Saul through the eyes of God. We are all His children, Created by Him. And if God created your enemy, surely there is something good in them. It may be buried under years of hurt and pain, but it is there waiting to be awakened or at least nudged by your Christ-Like attitude toward them.
