Never thought of this, but it makes sense: why not ask for the grace to accept God's mercy and abundant love for us? If we can pray "Lord, I believe; help my unbelief," then we can pray for this sort of thing, too.
Dear Heavenly Father, I bring my husband before you today asking that you would bless him and shape him into the man he was designed to be. Give him strength to lead our family, as Christ led the church with love and humility. Equip him with wisdom to make good decisions that are pleasing to you.
