Col 3:16  Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.

Eph 5:19  Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord;

Eph 5:20  Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ;

A child's cry touches a father's heart, and our King is the Father of his people. If we can do no more than cry it will bring omnipotence to our aid. A cry is the native language of a spiritually needy soul; it has done with fine phrases and long orations, and it takes to sobs and moans; and so, indeed, it grasps the most potent of all weapons, for heaven always yields to such artillery.
