What God promises He is able at any time to perform, and the work which He gives His people to do He is able to accomplish by them. If they will live according to every word He has spoken, every good word and promise will be fulfilled unto them. But if they come short of perfect obedience, the great and precious promises are afar off, and they cannot reach the fulfillment. (2T 148.1) MC VC

All that can be done in praying for the sick is to earnestly importune God in their behalf, and in perfect confidence rest the matter in His hands. If we regard iniquity in our hearts the Lord will not hear us. He can do what He will with His own. He will glorify Himself by working in and through them who wholly follow Him, so that it shall be known that it is the Lord and that their works are wrought in God. Said Christ: “If any man serve Me, him will My Father honor.” John 12:26. When we come to Him we should pray that we may enter into and accomplish His purpose, and that our desires and interests may be lost in His. We should acknowledge our acceptance of His will, not praying Him to concede to ours. It is better for us that God does not always answer our prayers just when we desire, and in just the manner we wish. He will do more and better for us than to accomplish all our wishes, for our wisdom is folly. (2T 148.2) MC VC

We have united in earnest prayer around the sickbed of men, women, and children, and have felt that they were given back to us from the dead in answer to our earnest prayers. In these prayers we thought we must be positive and, if we exercised faith, that we must ask for nothing less than life. We dared not say, “If it will glorify God,” fearing it would admit a semblance of doubt. We have anxiously watched those who have been given back, as it were, from the dead. We have seen some of these, especially youth, raised to health, and they have forgotten God, become dissolute in life, causing sorrow and anguish to parents and friends, and have become a shame to those who feared to pray. They lived not to honor and glorify God, but to curse Him with their lives of vice. (2T 148.3) MC VC
