Another reminder that the Gospel isn't something we hear and respond to once to get saved and them move away from it. We need it... I need it every day. Apparently Martin Luther needed it too...
"I myself have been preaching and cultivating [the Gospel of grace] through reading and writing for almost twenty years and still feel the old clinging dirt of wanting to deal so with God that I may contribute something so that He will give me His grace in exchange for my holiness." - Luther (Commentary on Galatians - as quoted by Scott Thomas in his book Gospel Coach.
Preach the Gospel to yourself.
"... we can say that the Gospel is just for non-Christians who don't know Jesus yet, and they need the Gospel. But for me, for us, those that are Christians, we need the Gospel every day." - Andrew Loewen [emphasis mine]
