“Jacob prevailed because he was persevering and determined. His experience testifies to the power of importunate prayer. It is now that we are to learn this lesson of prevailing prayer, of unyielding faith. The greatest victories to the church of Christ or to the individual Christian are not those that are gained by talent or education, by wealth or the favor of men. They are those victories that are gained in the audience chamber with God, when earnest, agonizing faith lays hold upon the mighty arm of power.” Ellen White
