Mat 22:36 “Teacher, which is the great commandment in the Law?” 37 And he said to him, “You shall love the Lord your God with all your heart and with all your soul and with all your mind. 38 This is the great and first commandment. 39 And a second is like it: You shall love your neighbor as yourself. 40 On these two commandments depend all the Law and the Prophets.”
Act 7:37 This is the Moses who said to the Israelites, ‘God will raise up for you a prophet like me from your brothers.’ 38 This is the one who was in the congregation in the wilderness with the angel who spoke to him at Mount Sinai, and with our fathers.

1Co 10:1 For I want you to know, brothers, ... 4 and all drank the same spiritual drink. For they drank from the spiritual Rock that followed them, and the Rock was Christ. 5 Nevertheless, with most of them God was not pleased, for they were overthrown in the wilderness. 6 Now these things took place as examples for us, that we might not desire evil as they did. ... 9 We must not put Christ to the test, as some of them did and were destroyed ... 11 Now these things happened to them as an example, but they were written down for our instruction, on whom the end of the ages has come. 12 Therefore let anyone who thinks that he stands take heed lest he fall. 3 No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation He will also provide the way of escape, that you may be able to endure it.
And no, God does not use doctors to heal diseases. Yes, they are good for setting bones and stitching up wounds, however, their poisons do not heal. Sure those poisons may mask the symptoms for a while, but eventually the disease manifests itself in the same form or in another form.
