We need the following quote- it is astoundingly easy to turn even our pursuit of spiritual maturity in on ourselves rather than keeping our eyes on the author and finisher of our faith.
The first thing to remember is that we must never separate the benefits (regeneration, justification, sanctification) from the Benefactor (Jesus Christ). The Christians who are most focused on their own spirituality may give the impression of being the most spiritual … but from the New Testament’s point of view, those who have almost forgotten about their own spirituality because their focus is so exclusively on their union with Jesus Christ and what He has accomplished are those who are growing and exhibiting fruitfulness. Historically speaking, whenever the piety of a particular group is focused on OUR spirituality that piety will eventually exhaust itself on its own resources. Only where our piety forgets about us and focuses on Jesus Christ will our piety nourished by the ongoing resources the Spirit brings to us from the source of all true piety, our Lord Jesus Christ. -Sinclair Ferguson
