Even the greatest saints have faced opposition and criticism. Evil abounds. What can be especially difficult are those enemies who speak well of you to your face but who lie and intrigue behind your back. These people refuse to deal with you directly. They deny there is a problem between you. Yet they are covertly working to harm you.
David wrote this psalm while in the midst of a conflict with people who were working against him. Yet he did not address the subject of his enemies until he had first affirmed that he would trust in God who was his rock and defense. It is always best to evaluate our problems in the light if who God is.
David knew that his enemies could not withstand God’s justice. David’s most vehement opponent was no match for his most faithful Defender. As a result, David refused to live with fear and worry. He knew he could trust his God. He knew the ultimate end of his enemies. He knew his enemies well. But he knew his God even better.
