Remove vexation from your heart, and put away pain from your body, for youth and the dawn of life are vanity. (Ecclesiastes 11:10 ESV)
Do not take to heart all the things that people say, lest you hear your servant cursing you. Your heart knows that many times you yourself have cursed others. (Ecclesiastes 7:21, 22 ESV)
Do not speak in the hearing of a fool,
for he will despise the good sense of your words. (Proverbs 23:9 ESV)
The Only Thing to Fear is God Himself
Though he slay me, I will hope in him;
yet I will argue my ways to his face. (Job 13:15 ESV)
"Dominion and fear are with God;
he makes peace in his high heaven.
Is there any number to his armies?
Upon whom does his light not arise?
How then can man be in the right before God?
How can he who is born of woman be pure?
Behold, even the moon is not bright,
and the stars are not pure in his eyes; (Job 25:2-5 ESV)
Having a relationship with God is very intimate. Likewise, I feel our bonds to one another should also be deep, faithful, loving, and profound. Each should strive to be the friend who sticks closer than a brother (Proverbs 18:24) and learn the important lessons God teaches us through those He places in our life.
Do not forsake your friend and your father's friend,
and do not go to your brother's house in the day of your calamity.
Better is a neighbor who is near
than a brother who is far away. (Proverbs 27:10 ESV)
