1. Do not fear perceived hostilities.
18 On the third day Joseph said to them, “Do this and you will live, for I fear God: 19 if you are honest men, let one of your brothers remain confined where you are in custody, and let the rest go and carry grain for the famine of your households, 20  and bring your youngest brother to me. So your words will be verified, and you shall not die.” . . .  
24 Then he turned away from them and wept. And he returned to them and spoke to them. And he took Simeon from them and bound him before their eyes. Genesis 42:18-24 (ESV)

11 My son, do not despise the LORD’s discipline or be weary of his reproof, 12 for the LORD reproves him whom he loves, as a father the son in whom he delights. Proverbs 3:11-12 (ESV)

2. Do not fear God’s intervention.
25 And Joseph gave orders to fill their bags with grain, and to replace every man’s money in his sack, and to give them provisions for the journey. This was done for them. 26 Then they loaded their donkeys with their grain and departed. 27 And as one of them opened his sack to give his donkey fodder at the lodging place, he saw his money in the mouth of his sack. 28 He said to his brothers, “My money has been put back; here it is in the mouth of my sack!” At this their hearts failed them, and they turned trembling to one another, saying, “What is this that God has done to us?”
Genesis 42:25-28 (ESV)

1 The wicked flee when no one pursues, but the righteous are bold as a lion. Proverbs 28:1 (ESV)

3. Do not fear possible outcomes.
29 When they came to Jacob their father in the land of Canaan, they told him all that had happened to them . . .  36 And Jacob their father said to them, “You have bereaved me of my children: Joseph is no more, and Simeon is no more, and now you would take Benjamin. All this has come against me.” 37 Then Reuben said to his father, “Kill my two sons if I do not bring him back to you. Put him in my hands, and I will bring him back to you.” 38 But he said, “My son shall not go down with you, for his brother is dead, and he is the only one left. If harm should happen to him on the journey that you are to make, you would bring down my gray hairs with sorrow to Sheol.”
Genesis 42:29-38 (ESV)

19 If you were of the world, the world would love you as its own; but because you are not of the world, but I chose you out of the world, therefore the world hates you. John 15:19 (ESV)

. . . Behold, I am with you and will keep you wherever you go, and will bring you back to this land. For I will not leave you until I have done what I have promised you.” Genesis 28:13-15 (ESV); Proverbs 23:24; 1 Kings 19:10

10 Godly sorrow brings repentance that leads to salvation and leaves no regret, but worldly sorrow brings death. 11 See what this godly sorrow has produced in you: what earnestness, what eagerness to clear yourselves, what indignation, what alarm, what longing, what concern, what readiness to see justice done. . . .2 Corinthians 7:10–11 (NIV)
