I thought about your question for a long time.
I suppose it is talking of two different things, a man who resists temptation and a man who endures trials which test his faith ...such as sickness and poverty, which are also brought about by disobedience to God. The world also persecutes those who are not of the world (1 Peter 4:4).
Would those adverse circumstances exist if people obeyed God as a nation.
In the curses for disobedience in Deuteronomy it lists those punishments for not obeying God's Law, which is the natural effect of disobeying God. It is cause and effect, Israel brought these circumstances upon themselves. Including sickness and poverty yet Christ healed the sick and ministered to the poor.
Deu 28:22 The LORD shall smite thee with a consumption, and with a fever, and with an inflammation, and with an extreme burning, and with the sword, and with blasting, and with mildew; and they shall pursue thee until thou perish.
Deu 28:33 The fruit of thy land, and all thy labours, shall a nation which thou knowest not eat up; and thou shalt be only oppressed and crushed alway:
Deu 28:48 Therefore shalt thou serve thine enemies which the LORD shall send against thee, in hunger, and in thirst, and in nakedness, and in want of all things: and he shall put a yoke of iron upon thy neck, until he have destroyed thee.
But these trials also bring us to Christ.
Heb 12:6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.
Heb 12:7 If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not?
2Ch 7:14 If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.
And Christ took our curses upon Himself.
1Pe 4:12 Beloved, do not be astonished by the burning among you taking place for a trial for you, as if a strange thing is happening to you,
1Pe 4:13 but just as you partake in the sufferings of Christ you rejoice, in order that also in the revelation of His honor, exulting you would rejoice.
1Pe 1:6 In which you must rejoice, if for a short time now it is necessary being pained by various trials,
1Pe 1:7 in order that the test of your faith, much more valuable than gold which is destroyed even being tested by fire, would be found in praise and honor and dignity at the revelation of Yahshua Christ,
...and a flaming sword which turned every way, to keep the way of the tree of life.
