Perhaps one of the most important pieces of 2 Timothy 1 is the phrase, "What you heard from me, keep as the pattern of sound teaching, with faith and love in Christ Jesus." This is a pretty good encapsulation of what religion should be in the Kingdom of Jesus: what came from Jesus, passed through the disciples, and continued being handed along through generations is that same pattern of sound teaching we pursue today. And of course, the working of the Spirit is part of that.
