God's covenant (and the promises it contains) is Truth. It is not
dependent on feelings. Emotions change. Truth does not change.
When feelings overwhelm you, override them with Truth. It is not
easy, however, you can do it. It takes determination and strength.
You provide the determination. God will help you with the strength.
It will change you for the better. That is how Truth works.
You gave them bread from heaven when they were hungry and water
from the rock when they were thirsty. You commanded them to go and
take possession of the land you had sworn to give them. But our
ancestors were a proud and stubborn lot, and they refused to obey
your commands. "They refused to listen and did not remember the
miracles you had done for them. Instead, they rebelled and appointed
a leader to take them back to their slavery in Egypt! But you are a
God of forgiveness, gracious and merciful, slow to become angry, and
full of unfailing love and mercy. You did not abandon them.
(Neh 9:15-17 NLT)
