The first point, we have to hold on and second point - God is just.
Eliphaz, one of the friends of Job. Job also sacrifice for his children. Sometimes were discourage to the things around us, just like Job, and he wants to die. God works in us in every situation of our lives.
Dismayed means frustrated.
We should not be like Eliphaz. God disciplined Job to his trust and faith in Him.
Psalm 145:14 The LORD upholds all who fall
and lifts up all who are bowed down.
1 Thessalonians 5:14 And we urge you, brothers and sisters, warn those who are idle and disruptive, encourage the disheartened, help the weak, be patient with everyone.
Hebrews 12:12 Therefore, strengthen your feeble arms and weak knees.
If you sow wickedness, you will reap wickedness. If you marry, you will surely experience suffering. Job although he is good in the eyes of the Lord, but he also suffer. It is not true that if you suffer, you have committed sin or your not a good person.
Even good person experience pain cause we will continue to suffer while were living in this world.
Psalm 146:3-4 3 Do not put your trust in princes,
in human beings, who cannot save.
4 When their spirit departs, they return to the ground;
on that very day their plans come to nothing.
As believers, we should know that God works even we don't understand and don't lose hope. Knowing God is better than us knowing the answer.
