It is a lonely feeling when we perceive that no one cares. This is why so many people are active on social media. They are throwing out a huge volume of material in hopes that someone will care, so that they feel validated. Unfortunately, much of what is on social media is not worth caring about. So what is worth caring about? God cares about you. That is enough for Him. Living a life that you and others can be proud of and that is encouraging to others and that gives others confidence in you is worth caring about.
Lord, thank you for caring about me and help me to behave in such a way that people actually should care.
