God's Word reveals God and his will. What you want for yourself and those you pray for is more of God and more of his will. As you see him in his Word, pray that God would make this seen and known and loved in the lives of the people you pray for. And as you see his will, pray that God would cause it to be done in the lives of those you pray for. Thy will be done on earth as in heaven.
Contrived prayers seem inauthentic.
If we are so self-conscious that we try to craft our prayers with interesting turns of phrase, we will lose the power and reality of prayer. But do try to pray specific Biblical values for people, not worn out cliches and trite generalities that have no spiritual depth. Let him mourn for his sins and not be indifferent or unconcerned for his own soul. Work a meekness into his heart. Grant him to be hungry and thirsty for righteousness.
