Ajs21, I am praying for you. We all make mistakes. I pray that nothing comes of it and that you can have peace about it. Give yourself grace.
Ajs21, I am praying for you but I almost think it would be better for you to report to your supervisor what happened. It just feels to me like honesty and accountability is what the Lord would like to see in us. I am not saying you are dishonest or unaccountable — not at all. But I pray that the right thing happens in accordance with God’s will. May God’s grace be with you.
