As you received Christ Jesus the Lord, walk in him,
rooted in him and built upon him
and established in the faith as you were taught,
abounding in thanksgiving. (Col 2:6-15)

Walking in Christ, rooted in Christ, built on Christ—this passage reminds me of Saint Patrick’s Breastplate:

Christ, be with me, Christ before me, Christ behind me, Christ in me, Christ beneath me, Christ above me, Christ on my right, Christ on my left, Christ where I lie, Christ where I sit, Christ where I arise, Christ in the heart of everyone who thinks of me, Christ in the mouth of everyone who speaks of me, Christ in every eye that sees me, Christ in every ear that hears me. (from The Breastplate of Saint Patrick)
