room? That was just like you Salvation-Army people, you always make a demonstration. Why could he not have gone into an inner chamber and prayed?" Because he would be thorough for his God in adversity, in the face of his enemies, as he was in prosperity. So he went and prayed with open window to the God of Heaven, and because _He is_ the God of Heaven, He is able to take care of His own. His heart was perfect towards the Lord his God. 3. _This perfect heart is perfect in its trust_:--and, perhaps, that ought to have come first, for it is the very root of all. Oh, how beautiful Abraham was in the eyes of God; how God gloried over him. How do I know that Abraham had a perfect heart towards God? Because he trusted Him. No other proof--no less proof--would have been of any use. I dare say he was compassed with infirmities, had many erroneous views, manward and earthward, but his heart was perfect towards God. Do you think God would have failed in His promise to Abraham? Abraham trusted Him almost to the blood of Isaac, and God showed Himself strong in his behalf, and delivered him, and made him the father of the faithful; crowned him with everlasting honor, so that his name, from generation to generation, has been a pillar of strength to the Lord's people, and a crown of glory to his God. CHAPTER IX. HOW TO WORK FOR GOD WITH SUCCESS. Son, go work to-day in my vineyard.--MATT. xxi. 28. Compel them to come in, that my house may be filled.--LUKE xiv. 23. I am to speak of some needful qualifications for successful labor; and I say:-- First, that there are certain laws which govern success in the kingdom of grace as well as in the kingdom of nature, and you must study these laws, and adapt yourself to them. It would be in vain for the husbandman to scatter his seed over the unbroken ground or on pre-occupied soil. You must plough and harrow and put your seed in carefully, and in proper proportion, and at the right time, and then you must water and weed and wait for the harvest. And just so in Divine things. Oh! we shall find out, by-and-by, that the laws of the spiritual kingdom are quite as certain and unerring in their operation as the laws of the natural kingdom, and, perhaps, a great deal more so; but, through the blindness and obtuseness and unbelief of our hearts, we could not, or would not find them out. People get up and fluster about, and expect to be able to work for God without any thought or care or trouble. For the learning of earthly professions they will give years of labor and thought, but in work for God they do not seem to think it worth while to take the trouble to think and ponder, to plan and experiment, to try means, to pray and wrestle with God for wisdom. Oh! no: they will not be at the _trouble_. Then they fail, grow discouraged, and give up.
