Colossians 3:1-2, 16

Therefore if you have been raised with Christ [to a new life, sharing in His resurrection from the dead], keep seeking the things that are above, where Christ is, seated at the right hand of God. [Ps 110:1] Set your mind and keep focused habitually on the things above [the heavenly things], not on things that are on the earth [which have only temporal value].

Let the [spoken] word of Christ have its home within you [dwelling in your heart and mind—permeating every aspect of your being] as you teach [spiritual things] and admonish and train one another with all wisdom, singing psalms and hymns and spiritual songs with thankfulness in your hearts to God.
