"Although for ages sin has been strengthening its hold on the human race, although through falsehood and artifice Satan has cast the black shadow of his interpretation upon the word of God, and has caused men to doubt His goodness; yet the Father's mercy and love have not ceased to flow earthward in rich currents. If human beings would open the windows of the soul heavenward, in appreciation of the divine gifts, a flood of healing virtue would pour in. MH 116.1"
"Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the Lord of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it."
The EGW passage explicitly alludes to Malachi 3:10 by using the phrase 'open the windows of the soul heavenward' and referencing a 'flood of healing virtue' pouring in, mirroring the promise of God opening the windows of heaven and pouring out a blessing in Malachi.
"The physician who desires to be an acceptable co-worker with Christ will strive to become efficient in every feature of his work. He will study diligently, that he may be well qualified for the responsibilities of his profession, and will constantly endeavor to reach a higher standard, seeking for increased knowledge, greater skill, and deeper discernment. Every physician should realize that he who does weak, inefficient work is not only doing injury to the sick, but is also doing injustice to his fellow physicians. The physician who is satisfied with a low standard of skill and knowledge not only belittles the medical profession, but does dishonor to Christ, the Chief Physician. MH 116.2"
"Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth."
Both passages emphasize the importance of diligent study and striving for excellence in one's calling, to be approved by God. The EGW passage applies this principle specifically to physicians.
"Those who find that they are unfitted for medical work should choose some other employment. Those who are well adapted to care for the sick, but whose education and medical qualifications are limited, would do well to take up the humbler parts of the work, ministering faithfully as nurses. By patient service under skillful physicians they may be constantly learning, and by improving every opportunity to acquire knowledge they may in time become fully qualified for the work of a physician. Let the younger physicians, “as workers together with Him [the Chief Physician], ... receive not the grace of God in vain, ... giving no offense in anything, that the ministry [of the sick] be not blamed: but in all things approving ourselves as the ministers of God.” 2 Corinthians 6:1-4 . MH 116.3"
"We then, as workers together with him, beseech you also that ye receive not the grace of God in vain."
The EGW passage directly quotes 2 Corinthians 6:1, making it a clear and explicit allusion.
"We then, as workers together with him, beseech you also that ye receive not the grace of God in vain. (For he saith, I have heard thee in a time accepted, and in the day of salvation have I succoured thee: behold, now is the accepted time; behold, now is the day of salvation.) Giving no offence in any thing, that the ministry be not blamed: But in all things approving ourselves as the ministers of God, in much patience, in afflictions, in necessities, in distresses,"
Ellen White directly references 2 Corinthians 6:1-4 in this passage.
"For the body is not one member, but many. If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body? And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body? If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling? But now hath God set the members every one of them in the body, as it hath pleased him. And if they were all one member, where were the body? But now are they many members, yet but one body. And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you. Nay, much more those members of the body, which seem to be more feeble, are necessary: And those members of the body, which we think to be less honourable, upon these we bestow more abundant honour; and our uncomely parts have more abundant comeliness. For our comely parts have no need: but God hath tempered the body together, having given more abundant honour to that part which lacked: That there should be no schism in the body; but that the members should have the same care one for another. And whether one member suffer, all the members suffer with it; or one member be honoured, all the members rejoice with it."
Both passages discuss the importance of different roles and functions within a larger body (the church or a medical team), and how each part is necessary and should work together harmoniously. The EGW passage applies this to the medical field, while 1 Corinthians 12 speaks of the church.
