You will hear from the pulpit that the Gospel is simple–so simple a child can understand. You’ll hear that Jesus wants nothing from you but belief, that all the work has already been accomplish through his life, death, and resurrection.
Just as I am thou wilt receive,
Wilt welcome, pardon, cleanse, relieve.
It’s theologically accurate (according to those who consider it accurate), but it’s not the full picture of the Christian(ly) life. After regeneration comes growth in grace and knowledge, conformity to the image of Christ, slow transformation into the ideal version of oneself. This happens by the work of the Spirit, through the spiritual disciplines. The disciplines are how Christians abide with Christ.
Some Christianly Spiritual Disciplines:
Scripture (reading meditating memorizing)
Prayer (habitual liturgic fasting)
Worship (private public artistic)
Agape (love without condition)
From a secular point of view the disciplines exercise certain cognitive mechanisms that seem to help people overcome obstacles and thrive at life. Quite a few studies suggest interesting benefits from habitual mediation, for example. There aren’t a lot of studies on the effects of Christian disciplines. I think “eastern” practises appeal to the secular west because they don’t carry the baggage of being part of the religion of our forefathers.
Also, you don’t need to believe in Buddha to do Anapanasati.
Maybe you don’t need to believe in the Christian stories to partake in their disciplines, either.
I like the idea of sanctification–slowly but surely growing into a wiser and more virtuous version of myself. I often wonder if this transformation is the essence of spirituality. I sometimes hear people disparage those who don’t chose a religion but still call themselves spiritual. I don’t think you need to be religious to be spiritual, but the runner trains for the race, working daily to refine and empower their performance. Surely some discipline is involved in any spiritual path.
