Psalm 35:7: For they have secretly spread a net for me without a cause; without any cause they have dug a pit for my soul.
This is one of those psalms you read and maybe begin to question whether the writer is saying the right things...
When we have things done against us, we may not be able to do anything about them because of the circumstances. But God can do things.
When we ask for bad things to happen against others, God may well not answer us in the way we wish because he knows what is in the hearts of everyone; but you can be very sure he is listening and will answer in one form or another.
Allow God to see you are trusting him with you true feeling by being honest and open to him. Don't try and hide things because you are afraid it is not the right thing to say to him!
