We often hear in marriage counsels that husbands and wives who have been established in God actually become one flesh and move in unison to realize God's love in daily life. A good marriage relationship will make each party involved, husband and wife, grow into a better person according to His will. That is the commensurate relationship that is realized in the relationship.
This understanding is also implied in our reading this time. Psalm 45:1-10 expresses praise, hope, and prayer regarding the king. The poem then continues with advice to the king's future consort. This further clarifies the use of the text as a poem of praise at the king's wedding. The advice to the future queen consort begins with a suggestion to untie the knot with her nation and family. This was important because several times the kings of Israel fell into disbelief under the influence of their foreign wives, and pagan nations. He and the King became one "team", God's mandate to bring about governance based on His will.
The psalmist continues his verse by encouraging the queen with a statement that contains a promise and arouses the hope of the future queen to partake in the honor bestowed upon the king. Both from within and without the land, people will come bringing gifts to the king.
This verse of praise to the King and Queen also echoes a message for us in our domestic life. Just as the King and Queen of Israel were mandated to declare God's purpose in their lives, so too are we invited by God to realize His will. The process of realizing His will in married life begins with a willingness to grow into a partner who is compatible and complementary. It is in such a life that we can agree with the psalmist's call in verse 18 that in the end only the name of the Lord will be magnified.
