A Wedding Prayer

This was for Brad Belschner's wedding, where I was asked to pray for the new couple's role in their church and community:

O Triune God, Father, Son, and Holy Spirit, who have united in one body people of every tribe and nation and tongue in your Church, we thank you that today you unite in one flesh Brad and Sarah, born of different nations, and brought together today from across many lands and a wide sea. We thank you that they have been united in your Church, by your Church, for your Church, and as a sacrament of that blessed marriage between Christ and the Church.
We pray today that they would never forget this high calling and purpose of their marriage, that they might not only give themselves for one another and for you, but for all your people, in this congregation, this nation, and the world. To each of them you have given great gifts, gifts of knowledge, of love and compassion, of patience and diligence, and we pray that, by uniting these gifts today, your Spirit would make them wiser, more powerful, and more tireless in their service of your people than they would ever have been alone.

We pray that you would use their knowledge and the great power of their minds to understand your Word in fresh and powerful ways, and to illumine those around them with the wisdom they glean. We pray that they may take every thought captive to the obedience of Christ, and cast down strongholds of unbelief in their community, their country, and the world.
We pray that you would use their deep love and compassion to reach out to the needy of this city, and of every place in which they find themselves. Enable them to follow Christ on the hard road of self-sacrifice and number themselves with the poor and the lowly, for on the side of the oppressors there is power, and the weak have no comforter.
And because these tasks are endless, O Lord, for the power of unbelief is stubborn, and the tears of the oppressed are without number, we pray that you would strengthen them with ever greater gifts of patience and diligence, that they would never grow weary in doing good. For Lord, we know that “Even youths shall faint and be weary, and young men shall utterly fall; but they that wait upon the Lord shall renew their strength; they shall mount up on wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.” And so, Lord, we pray to you today for the blessings of your wings upon Brad and Sarah; to shelter them when they are afraid, to raise them up when they are weary, and to speed them on the road you have laid before them; through Jesus Christ our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, one God, world without end. Amen.
