Personally, you should not be asking this in an online app. Because it’s for religion and you should base it on your own experiences.
But anyway, Personally, My gratitude for God is massive. Him keeping me alive and giving me enough food and protection is enough, the pandemic is almost 3 years and i’ve never been affected or infected by any virus. I’m very thankful that i know that You (God) are her for me and that You’re letting me know that you will never abandon me. Because that you have great power, i know that You ahve the best comfort other that human beings.
