Prayer of the Apostle Paul (Ephesians 3: 14 - 19)

I kneel before the Father, from Whom every family in heaven and on earth is named, that He may grant you in accord with the riches of His glory to be strengthened with power through His Spirit in the inner self, and that Christ may dwell in your hearts through faith; that you, rooted and grounded in love, may have strength to comprehend with all the holy ones what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge, so that you may be filled with all the fullness of God.

"O Lord Jesus Christ, how good, blissful and desirable it is to feel the violence of Your love! Ah! enlighten my heart every day with the rays of this love, dissipate the darkness of my mind, illuminate the secret places in my heart, strengthen and inflame my intellect, and rejoice and fortify my soul! Oh! how tender is Your mercy, how great and sweet Your love, O Lord Jesus Christ. You lavish Your love to be enjoyed by those who love none but You, and who think of nothing buy You! Loving us first, You invite us to love You; You delight us and draw us, so great is the power of Your love. Nothing invites us, nothing delights and attracts us more than this kind attention of love; the heart, which at first was torpid, feels itself inflamed; and the heart that is fervent, when it knows it is loved and has been loved by You, it becomes still more ardent.

"O most loving Lord Jesus Christ, although You have loved me inexpressibly, I, a wicked sinner, enclosing in my bosom a heart of stone and iron, have not recognized Your burning love; and even though I desired Your affection, I did not want to love You. Deign, then, to come to my aid, O most merciful Lord Jesus Christ, and by the violence of Your most sweet love, force my rebellious soul to love You, so that I may serve You in peace and attain the unending life of love"

Ven. R. Giordano

The akathist is one of the most ancient ornces or collection of prayers in the Byzantine Church. It is a prayer of veneration, thanksgiving and petition. "Akathist" means standing because it is an expression of profound joy in recognizing the honor being paid to Our Lord, Our Lady, or the saint who is being venerated. An akathist, therefore, is prayed standing.
(From Byzantines.net)

This particular akathist is especialy beautiful and fitting in this time of lent. I am including a pdf version of it for those of you who want to pray it yourself

Jesus, God, Eternal Love, Who was pleased to save us who are born of earth!
Jesus, Infinite Mercy, Who didst come down here to us fallen creatures!
Jesus, Who was clothed in our flesh and didst destroy the dominion of death by Thy death!
Jesus, Who dost deify us with Thy Divine Mysteries!
Jesus, Who hast redeemed the whole world by Thy Cross and Passion!
Jesus, Son of God, remember us when Thou comest in Thy Kingdom!

I have found this Orthodox prayer. It is beautiful and I just thought to share it with the rest of the world.

Prayer of Metropolitan Philaret

Lord, give me the strength to greet the coming day in peace. Help me in all things to rely on Your holy will. Reveal Your will to me every hour of the day. Bless my dealings with all people. Teach me to treat all people who come to me throughout the day with peace of soul and with firm conviction that Your will governs all. In all my deeds and words guide my thoughts and feelings. In unexpected events, let me not forget that all are sent by you. Teach me to act firmly and wisely, without embittering and embarrassing others. Give me the physical strength to bear the labors of this day. Direct my will, teach me to pray, pray in me. Amen.
