Recognition Example #1: You see someone and you know that you know them.
Recognition Example #2: You see someone and whether you know them or not, you acknowledge their existence with some sort of action (from saying hello to a simple "eye contact and head nod").
Sometimes we don't recognize people (example #1) because we may not know them or we just don't remember that we know them. And then sometimes we don't take the time or make the effort to acknowledge that someone exists (example #2).
Lord, help me to have a relationship with you in such a way that I will always recognize you (know you) and also recognize (acknowledge) who you are.
