The goal of these excercises is to get each of us into God's Word and see what He has to say on various topics. If you do a word search for "one another" and focus on the Epistles, you will find well over 20 examples of how we should - or shouldn't - interact with each other. Here's an example of what we should be doing:
"but through love serve one another." (Galatians 5:13b, ESV)
This statement is almost immediately followed by something we ought to...avoid :-) "But if you bite and devour one another, watch out that you are not consumed by one another." (Galatians 5:15, ESV)
These are fun statements to study. The key application question was, which one of these will you seek to emply this week (or, in the near future)? I'd love to hear how you applied this, feel free to drop me an email!
