Happy to see Ephesians 5 given a guernsey but too much sentimental goo in these suggestions. Also, oaths in the Bible are serious things, lets be careful to not over-promise.
With deepest joy I receive you into my life that together we may be one. As is Christ to His body, the church, so I will be to you a loving and faithful husband. Always will I perform my headship over you even as Christ does over me, knowing that His Lordship is one of the holiest desires for my life. I promise you my deepest love, my fullest devotion, my tenderest care.
______, I love you. Today is a very special day. Long ago you were just a dream and a prayer. This day like a dream come true the Lord Himself has answered that prayer
I love you and I know you love me. I am confident that God has chosen you to be my husband.
