So great are the world’s needs, that not all who are called to be medical missionary evangelists can afford to spend years in preparation before beginning to do actual field work. Soon doors now open to the gospel messenger will be forever closed. God calls upon many who are prepared to do acceptable service, to carry the message now, not waiting for further preparation; for while some delay, the enemy may take possession of fields now open. (CT 469.1) MC VC

I have been instructed that little companies who have received a suitable training in evangelical and medical missionary lines should go forth to do the work to which Christ appointed His disciples. Let them labor as evangelists, scattering our publications, talking of the truth to those they meet, praying for the sick, and, if need be, treating them, not with drugs, but with nature’s remedies, ever realizing their dependence on God. As they unite in the work of teaching and healing they will reap a rich harvest of souls. (CT 469.2) MC VC

And while God is calling upon young men and women who have already gained a practical knowledge of how to treat the sick, to labor as gospel medical missionaries in connection with experienced evangelical workers, He is also calling for many recruits to enter our medical missionary training schools to gain a speedy and thorough preparation for service. Some need not spend so long a time in these schools as do others. It is not in harmony with God’s purpose that all should plan to spend exactly the same length of time, whether three, four, or five years, in preparation, before beginning to engage in active field work. Some, after studying for a time, can develop more rapidly by working along practical lines in different places, under the supervision of experienced leaders, than they could by remaining in an institution. As they advance in knowledge and ability, some of these will find it much to their advantage to return to one of our sanitarium training schools for more instruction. Thus they will become efficient medical missionaries, prepared for trying emergencies. (CT 469.3) MC VC
