Τῇ προσευχῇ προσκαρτερεῖτε, γρηγοροῦντες ἐν αὐτῇ ἐν εὐχαριστίᾳ (Colossians 4:2)
“Devote yourselves to prayer.” (Colossians 4:2, NAS, NIV, NRSV) Or the ESV, “continue steadfastly in prayer, being watchful in it with thanksgiving” (“continue earnestly” NKJV).
Paul likewise urges devotion to prayer in Romans 12:12. The disciples of Christ, in the days following Christ’s ascension, were “devoting themselves to prayer” (Acts 1:14). They “devoted themselves to the apostle’s teaching and the fellowship, to the breaking of bread and the prayers” (Acts 2:42).
To “devote” oneself means to give oneself to something with such dogged commitment that one becomes known, even identified, by that devotion. A husband devoted to his wife has eyes and time for no other woman. A teacher devoted to his or her students is committed, in and out of the classroom, that the students would learn and flourish. A fan devoted to his favorite college or professional team wears his team colors on game day, loves to talk about his team, and senses the joys of winning and the pain of defeat along with the players.
Christians are called to devote themselves to prayer. To be devoted to prayer means to commit ourselves to prayer in such a way that our lives (not merely our pre-meal rituals) are defined by prayer. Being devoted to prayer means that our eyes are on God and the moments in our days are filled with prayer. Being devoted to prayer means that we make every effort to battle for souls, our own and those of others, asking, knocking, and seeking God’s work. Being devoted to prayer means that we will be marked by an obvious, fanatical, intense, and unwavering practice of prayer.
