Do you mean 'Is this right?' or 'Is this correct?'. We use 'true' for facts. (For example, 'Is it true that you're getting married?') If you are asking about the grammar or vocabulary, you say 'right' or 'correct'. I'm afraid it is not clear what you mean by 'I tested the sense today.' In the second part of your sentence, do you mean this? : '... I asked God to protect the people I love.'
