And those who haven't read the other story.
I was young with two small kids. My husband decided to move in with a girl he met at the store. I had a part time job making $400 a month. I prayed to God to give me wisdom. He told me in my heart, and in the Bible to put God first in everything even my money, so I did. I gave 10 % to the church which was going to make me low on my rent in 3 weeks. But in the Bible, book of Micah, it says "I challenge you to trust me, give me your first and I will pour down heaven for you" so I trusted him. After 2 weeks I received a knock on my door. A lady that I had given a ride to visit her friend in a nursing home a couple of times had died she said, and she wanted to give me all the money from the gift she had inherited from her friend $22,000. I could pay my rent. God never fails us...I have challenged God by putting all my eggs in Jesus basket. It was the right basket!
Speaking from the heart is great, but abuse is never ok. We should always be loving.
