Here are 6 powerful but short prayers that I hope can help strengthen your marriage.
Prayer for Unity in the Spirit
God, my Father, I know that my beloved is so different from me and I am supposed to learn how to dwell with my spouse in the unity of the Spirit, and I need Your Spirit to help me know how we can both be of one mind and to grow together in Christ. This is not possible without Your Spirit, God, so help me in ways that are reflective of the similar relationship that the church has with the Head of the Church, Jesus Christ, in Whose righteous name I pray.
Prayer of Thanksgiving
Great heavenly Father, just as our children are a gift from You, so too is my precious spouse. You have been so good to me, for he/she is such a blessing to me and more than I truly deserve, so I praise You for him/her and thank You for this blessed spouse that You sovereignly directed to me. My life is so much richer for him/her, and I thank You, Lord, for this blessing. In the precious name of Christ I pray.
