We never grow BEYOND the Gospel - instead we should grow deeper INTO the Gospel, becoming immersed in it. Many Christians mistakenly believe that they outgrow the Gospel and need something deeper - so they gravitate toward various "deep" Christianly things or studies - but the truth is we need to be moving ever more deeply into the deep truths of the Gospel and the implications for our lives. The Gospel is not merely the introduction to the Christian faith - it is actually the main story line!!! Understanding this leads to your deepest hunger being satisfied.
