Outside this communion, these qualities are unattainable for them. Therefore it would be pride and self-deception on their part to dream of any outside mediation, apart from Jesus Christ (Col 2:18-19), in the work of reconciliation with God" (N. Mukhin).
The giving of peace and grace is customary in Paul's opening greetings. Yet for the Colossians, disturbed by the rumors of false teachers, peace could be especially precious. Through it they could calmly consider the state of affairs and determine their relations and actions.
Grace, as God's merciful gift, is needed for everything and is especially necessary for progress in faith and spiritual life. It could pour strength and contentment into troubled hearts and minds.
With such strength and contentment, 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 wishes 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 close. Therefore the Apostle prayed unceasingly for the Colossians, offering thanksgiving to God for their progress.
He was not personally able to act upon the Colossians because of his far distance from them. By prayer he expressed the highest and most effective communion with them.
By telling them this, he teaches them the same. In particular, he obliges them to pray both for him, an innocent prisoner, and for themselves. Their faith and holy life faced temptations from weak brethren, and especially from false teachers.
According to Saint John Chrysostom, "The Apostle shows his love for them not only by thanksgiving, but also by unceasing prayer."
Bishop Theophan develops Chrysostom's thought and raises everything to unity: "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 beget 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 when praying, he thanks God for them" (Bishop Theophan).
