Orthodox Prayer for Brother or Sister

O Lord Jesus Christ, our sweet Savior, Who hast commanded us, saying, Love ye one another, even as I have loved you, kindle in my whole being the holy flame of love of Thee and my neighbor, that in all things I may do Thy will.

O holy Lord, keep also my brother(s) and sister(s) ever in this holy love. Grant them wisdom, health, a good life, and Thy Divine grace, so that they may walk in Thy ways and do those things that are well-pleasing to Thee. O sweetest Lord Jesus, help us by Thy grace, so that from this time until the end of our life we may love one another, for What is more good and more beautiful than for brothers to live together in unity? Thus, O Lord, hear our prayer and be Thou merciful unto us.

For Thou art good, merciful, and the Lover of men, and to Thee do we ascribe glory: to the Father, and to the Son, and to the Holy Spirit, both now and ever and unto ages of ages. Amen.
