mysterious messages

over the last few weeks, i've been getting these random text messages on my phone, usually around 8am. they are encouraging messages, like "glorious morning!" and "amazingly beautiful day! great and awesome is our God!!!" i got another this morning, so on my way home, i texted the phone number to ask for the person's identity. all they replied with was, "someone who loves the Lord." while it's lovely to be encouraged, it's also a little odd that it's anonymous.
