When surrounded by old friends and family, it can be easy to linger in the "glory days". For some its reminiscing and for others it's due to a desire to avoid seeming lame, uncool, or to prove that we still got it. When we linger in our "unholy days" we could potentially lose an opportunity to share testimony. This is when our "glory days" do not glorify Jesus at all, instead they boast in our old wicked ways.
