Psalms 35:14 I behaved myself as though he had been my friend or brother: I bowed down heavily, as one that mourneth for his mother.
Respond With Right Not Revenge.
What Motivates Your Behavior.
David speaks of his behavior being much different than that of his enemies. They rewarded him with evil for the good he accomplished. He reacted differently however when they were in time of need. He humbled himself with fasting and prayed for their deliverance. He responded with right not revenge.
Others may not treat you properly. They may even seek your downfall but it is essential you do respond in the same manner. Learn to react with God's love and patience basing your actions on truth and not retaliation. Trust the Lord to defend you as you consistently look to him for your protection and provision.
