Therefore, it would be pride and self-delusion for them to dream of any outside mediation, apart from Jesus Christ (Col 2:18-19), in the work of reconciliation with God.
The bestowal of peace and grace is customary in Paul's opening greetings. Yet for the Colossians, troubled by the talk of false teachers, peace could be especially precious. It would enable them calmly to consider the state of things and determine their relations and actions. Grace, as God's merciful gift, necessary for everything and especially for progress in faith and spiritual life, could pour strength and sufficiency into troubled hearts and minds. With these, every struggle could become not dangerous, but even fruitful, strengthening them in courage and patience.
The first work of spiritual life and communion is prayer to God. It is especially necessary when one desires to act upon others across distances that serve as an insurmountable barrier to communion. In God and through God, all who turn to Him for His almighty help can be near.
For this reason the Apostle prayed unceasingly for the Colossians. He offered thanksgiving to God for their progress, since he himself could not act personally upon them because of his distant absence. By this he expressed the highest and most effective communion with them. By telling them this, he also teaches them to do the same.
In particular, he obliges them to pray both for him, an innocent prisoner, and for themselves. This was all the more necessary because temptations awaited their faith and holy life, both from weak brethren and especially from false teachers.
According to St. John Chrysostom, "the Apostle shows his love for them not only by thanksgiving, but also by unceasing prayer." The Right Reverend Theophan develops Chrysostom's thought and brings everything to unity. He says: "The Father of our Lord is also our Father by grace. Believers are one with Christ the Lord, and He is one with the Father. As there is no mediation between God the Father and the Lord, so there is none between believers and Christ the Lord. 'Our Father!' believers cry, and the Spirit moves their hearts to cry: 'Abba, Father!' With sweet words the Apostle began his epistle, words that give birth to sweet thoughts and feelings."
As for the unceasing character of prayer, it may be understood in this sense: "Every time he prays, he prays for them, and while praying, he thanks God for them" (Right Reverend Theophan).
