All that believers have is undoubtedly of grace. Their repentance, faith, and holiness, are all the gift of God. But the degree to which a believer attains in grace, is ever set before us as closely connected with his own diligence in the use of means, and his own faithfulness in living fully up to the light and knowledge which he possesses. Indolence and laziness are always discouraged in God’s word. Labor and pains in hearing, reading, and prayer, are always represented as bringing their own reward. “The soul of the diligent shall be made fat.” (Prov. 13:4.) “An idle soul shall suffer hunger.” (Prov. 19:15.)
