Before addressing the actual error, I'd like to draw your attention to a couple of other potential problems:

Your file is stored in the /run filesystem which is normally a tmpfs filesystem, i.e. a RAM-disk. That file will not survive a power cycle and it will allocate your RAM. I suggest you move it to your SDD/HDD.

Also, you're trying to mount the file in the folder containing the said file. You will probably, at some point, get an error message from mount telling you that the mount point isn't empty. I suggest you create a folder called /mnt/Jesus and keep it empty for this purpose.

Now to your actual error. You haven't shared any details of the contents of this file but I assume it's a complete disk image rather than an image of a single partition? You have to perform some additional commands to make it work.

1) Read the partition table from the image with "fdisk -l /run/Jesus/Jesus"

2) Identify the partition containing the filesystem you want to mount and make note of the start sector

3) Mount that partition with "mount -o loop,offset=$((nnn * 512)) /run/Jesus/Jesus /mnt/Jesus". Replace nnn with the start sector from step 2. The "512" is the sector size and should match the output from fdisk in step 1.
