"Not all understand these principles. Many who seek the Lord's healing mercy think that they must have a direct and immediate answer to their prayers or their faith is defective. For this reason, those who are weakened by disease need to be counseled wisely, that they may act with discretion. They should not disregard their duty to the friends who may survive them, or neglect to employ nature's agencies for the restoration of health. MH 231.1 Often there is danger of error here. Believing that they will be healed in answer to prayer, some fear to do anything that might seem to indicate a lack of faith. But they should not neglect to set their affairs in order as they would desire to do if they expected to be removed by death. Nor should they fear to utter words of encouragement or counsel which at the parting hour they wish to speak to their loved ones. MH 231.2"
"And Isaiah said, Take a lump of figs. And they took and laid it on the boil, and he recovered."
Both passages illustrate that seeking divine healing does not preclude using practical means. 2 Kings 20:7 shows Isaiah prescribing a natural remedy (figs) for Hezekiah's boil, while EGW argues against neglecting natural agencies for health restoration, even while praying for healing. The parallel lies in the integration of faith and practical action.
"Those who seek healing by prayer should not neglect to make use of the remedial agencies within their reach. It is not a denial of faith to use such remedies as God has provided to alleviate pain and to aid nature in her work of restoration. It is no denial of faith to co-operate with God, and to place themselves in the condition most favorable to recovery. God has put it in our power to obtain a knowledge of the laws of life. This knowledge has been placed within our reach for use. We should employ every facility for the restoration of health, taking every advantage possible, working in harmony with natural laws. When we have prayed for the recovery of the sick, we can work with all the more energy, thanking God that we have the privilege of co- operating with Him, and asking His blessing on the means which He Himself has provided. MH 231.3"
"For as the body without the spirit is dead, so faith without works is dead also."
EGW's argument that using remedial agencies doesn't negate faith, but rather complements it, directly reflects the principle of James 2:26 that faith without works is dead. Both emphasize the necessity of action alongside belief.
