Psalms 7:10 My shield is from God, who saves those who are upright in heart.
Having called on God to treat both himself and his enemies with the same justice, the psalmist now boasts of a protective shield from God. The Lord will act to right the wrongs inflicted on his servant. The Lord will save and vindicate those who are upright in heart.
Loyalty to Christ in an age like this one will require praying like this. We will have many enemies who claim we are being unjust, who will claim to be genuine, and accuse us of being hypocritical. We must trust in the shield of God. We must pray through those terrible accusations.
