How can you be thankful you are homeless. Sure I can be thankful I am alive and have a van that wants to run halfway right. However, seriously how can you be greatful and happy and thankful when your life is falling apart?
So sorry for your situation. It is hard for someone like me to give you advice about trusting Lord while not experiencing what you have, but maybe you could meditate on these passages. In fact, ALL of Job might be helpful for you. Especially the ending.
Job 1:21 New King James Version (NKJV)
21 And he said:
“Naked I came from my mother’s womb,
And naked shall I return there.
The Lord gave, and the Lord has taken away;
Blessed be the name of the Lord.”
Philippians 4:11-13 New International Version (NIV)
11 I am not saying this because I am in need, for I have learned to be content whatever the circumstances. 12 I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. 13 I can do all this through him who gives me strength.
Be Blessed and at peace brother.
