The psalmist faced relentless attacks from his enemies. To David, it seemed like his enemies were stealing, killing and destroying at will. Our enemy does the same (John 10:10). David asked God to 1) deliver him (Ps 140:1) , and 2) guard him (Ps 140:4).
David’s conviction in God was a result of his communion with God.
“I know that the Lord will maintain the cause of the afflicted, and will bring about justice for the needy. The righteous will give thanks to your name; the upright shall dwell in your presence.” (Ps 140:12-13)
In these days of great sorrow and confusion, remember that we can say to Our Father, “You are my God, hear my pleas for mercy” (Ps 140:6). He hears and promises a purposeful and abundant life.
